Abstract
1332989 Quaternary immonium salts CHINOIN GYOGYSZER ES VEGYESZETI TERMEKEK GYARA RT 4 May 1971 12950/71 Heading C2C A process for the preparation of a quaternary immonium salt containing a cation of the general formula wherein R is an optionally substituted aralkyl group; R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> are optionally substituted alkyl groups, or R<SP>3</SP> is a hydrogen atom, or R<SP>1</SP> + R<SP>2</SP> or R<SP>1</SP> + R<SP>3</SP> together form a ring which may contain a hetero atom, which comprises reacting a quarternary ammonium salt containing a cation of the formula wherein R<SP>4</SP>, R<SP>5</SP> and R<SP>6</SP> are optionally substituted alkyl groups, with a compound of the formula The tertiary amine formed during the course of the reaction is preferably continuously removed from the reaction mixture either by heating, distillation or precipitation. The reaction may be carried out in a solvent at 20 to 210‹ C. Examples describe the preparation of benzyl - α - picolinium chloride and 2 - propyl- 4 - amino - 5 - pyrimidyl - methyl - α - picolinium-chloride dihydrochloride.
