Abstract
1365806 1(2H)-Phthalazinones M INOUE M ISHIKAWA T TSUCHIYA and T SHIMAMOTO 22 Feb 1972 [23 Feb 1971 27 Feb 1971 (3) 5 Aug 1971 10 Aug 1971 (2) 16 Aug 1971 21 Aug 1971 8 Sept 1971 9 Sept 1971] 8116/72 Heading C2C Novel 1(2H)-phthalazinones of the formula wherein R 1 is H or alkyl; R 2 is H, alkyl, cycloalkyl, alkenyl, aryl, aralkyl, dialkylaminoalkyl, furfuryl, 3-furylmethyl, pyridylmethyl or pyridyl; R 3 is H, alkyl, aryl, carbamoyl, alkylcarbamoyl, dialkylcarbamoyl, alkylsulphonyl, or arylsulphonyl; R 4 is H, halogen, alkyl or alkoxy; R 5 is H, halogen, alkyl, alkoxy, NH 2 , acylamino, alkoxycarbonyl, or carbamoyl; or R 1 and R 2 , together with the N atom to which they are attached, form a saturated heterocyclic ring optionally containing a further heteroatom; are prepared by one of the following methods: (a) compounds in which R 1 is H and R 2 is not H by reacting the appropriate 4- hydroxymethyl-1(2H)-phthalazinones with isocyanates of the formula R 2 NCO (R 2 not equal to H); (b) reacting compounds of Formula IV with compounds of the formula HNR 1 R 2 ; (c) reacting the appropriate 4-hydroxymethyl- 1(2H)-phthalazinones with phosgene and treating the resulting chloroformates with ammonia or amines of the formula HNR 1 R 2 ; (d) reacting the appropriate 4-hydroxymethyl-1(2H)-phthalazinones with carbamic acid derivatives of the formula R 1 R 2 NCOY, wherein Y is halogen, alkoxy, aryloxy, alkylthio or arylthio; (e) reacting compounds of the Formula VIII with hydrazines of the formula H 2 NNNR 3 . 4 - Phenoxycarbonyloxymethyl - 1(2H) - phthalazinone is obtained by reacting 4-hydroxymethyl-1(2H)-phthalazinone with phenyl chloroformate. o-Carbamoylbenzoylmethyl methylcarbamate is prepared by reacting methyl isocyanate with o-hydroxyacetyl benzamide resulting from the reaction between ammonia and 3,4-dihydro-4- oxo-isocoumarine. Pharmaceutical compositions comprise the novel compounds and pharmaceutically acceptable diluents or carriers. The compositions are suitable for the treatment of atherosclerotic and thrombotic diseases.
