Definitions
- the present invention relates to a novel solvate crystal.
- Olmesartan medoxomil which is an angiotensin II receptor antagonist, is useful as an active ingredient of a medicament for the treatment and prevention of hypertension (for example, Patent Documents 1 to 5 and Non-Patent Documents 1 and 2).
- Olmesartan medoxomil is produced from olmesartan through the following steps, but the final product precursor, trityl olmesartan medoxomil, achieves improved operability and efficient production of high purity final product. Therefore, it has been desired to obtain a new crystal.
- An object of the present invention is to provide a novel triethylolmesartan medoxomil acetone solvate crystal.

- any one of (13) to (17) The method as described in one. (20) The method according to any one of (13) to (19), wherein seed crystals are inoculated. (21) A method for producing olmesartan medoxomil, comprising a step of removing a trityl group from the crystal according to any one of (1) to (4). (22) The method according to (21), comprising the step according to (5). (23) The method according to (21), comprising the first step and the second step according to (13).
- olmesartan, trityl olmesartan medoxomil, olmesartan medoxomil, olmesartan medoxomil dehydrate, trityl halide, and DMDO halide each represent a compound represented by the structural formula described in the above figure.
- X independently represents a halogen atom such as chloro, bromo or iodo. Tr represents triphenylmethyl.
- DMDO represents a portion excluding X in the structural formula of DMDO halide.
- Trityl olmesartan represents a compound represented by the structural formula shown in the following figure.
- DMDO-Cl DMDO chloride
- Olmesartan 4- (1-hydroxy-1-methylethyl) -2-propyl-1-[[2 '-[1H-tetrazol-5-yl] biphenyl-4-yl] methyl] imidazole-5-carboxylic acid; Trityl olmesartan medoxomil: (5-methyl-2-oxo-1,3-dioxolen-4-yl) methyl 4- (1-hydroxy-1-methylethyl) -2-propyl-1-[[2 '-[2 -(Triphenylmethyl) -2H-tetrazol-5-yl] biphenyl-4-yl] methyl] imidazole-5-carboxylate; Olmesartan medoxomil: (5-methyl-2-oxo-1,3-dioxolen-4-yl) methyl 4- (1-hydroxy-1-methylethyl) -2-propyl-1-[[2 '-(1H- Tetrazol-5-yl
- the crystal of the present invention refers to a solid whose internal structure is composed of regularly repeated constituent atoms (or a group thereof) in a three-dimensional manner, and is distinguished from an amorphous solid that does not have such a regular internal structure. .
- crystals of the same compound may produce crystals (crystal polymorphs) having a plurality of different internal structures and physicochemical properties depending on the crystallization conditions. Any form may be sufficient and the mixture of two or more crystal polymorphs may be sufficient.
- Examples of the crystal form of the present invention include those showing the pattern of FIG. 1 or FIG. 2 by X-ray crystal diffraction, and those showing the pattern of FIG. 4 or FIG. 5 by thermal analysis, but of trityl olmesartan medoxomil.
- the acetone hydrate crystals are not limited to these.
- novel solvate crystals provided by the present invention are easy to handle and are useful as synthetic intermediates for olmesartan medoxomil.
- FIG. 2 is an X-ray crystal diffraction pattern of the crystal obtained in Example 1.
- FIG. The X-ray crystal diffraction pattern of the crystal obtained in Example 2.
- Olmesartan which is a starting material used in the production method of the present invention, can be easily produced according to the method described in Japanese Patent Publication No. 7-121918 (Patent No. 2082519; US Pat. No. 5,616,599).
- the acetone solvate crystal of trityl olmesartan medoxomil of the present invention can be obtained, for example, through the following steps.
- This step is a step for producing trityl olmesartan by reacting olmesartan with trityl halide in an acetone solvent in the presence of a base.
- trityl halide trityl chloride and trityl bromide are usually used, and trityl chloride is preferred.
- the reaction solvent is usually used in an amount of 5 to 20 (v / w) times that of olmesartan, but is not particularly limited.
- the base used is not particularly limited, but it is preferable to use amines such as triethylamine, diisopropylethylamine, pyridine, 1,8-diazabicyclo [5,4,0] -7-undecene (DBU), DBU is optimal.
- amines such as triethylamine, diisopropylethylamine, pyridine, 1,8-diazabicyclo [5,4,0] -7-undecene (DBU), DBU is optimal.
- the reaction temperature is not particularly limited, but is usually 0 ° C. to the boiling point of the solvent, and preferably 20 to 60 ° C.
- trityl olmesartan can be isolated by a method commonly used in the field of synthetic organic chemistry. It is preferable to do.
- This step is a step for producing trityl olmesartan medoxomil by reacting DMDO halide with trityl olmesartan in an acetone solvent in the presence of a base.
- DMDO halide DMDO chloride and DMDO bromide are usually used, and DMDO chloride is preferred.
- the base used is the same as the previous tritylation step, and DBU is preferred.
- the reaction temperature is not particularly limited, but is usually 0 ° C. to the boiling point of the solvent, and preferably 20 to 60 ° C.
- the amount of water contained in the reaction system can be usually adjusted by adding water to the reaction system. Water can be added at once in the tritylation step, but can also be added separately in the tritylation step and the DMDO esterification step.
