  • N-(4-Hydroxybenzyl)-3,4,5-trimethoxybenzamide and method for producing trimethobenzamide chlorohydrate
    Patent number: 4507499
    Abstract: The invention relates to a method for producing trimethobenzamide chlorohydrate.According to such a method, a chloromethilation is carried out on anisle and, after reaction with urotropine followed by acidic hydrolisis, 4-methoxybenzylamide chlorohydrate is obtained which, demethyilated by hydrazoic acid, provides 4-hydroxy benzylamine chlorohydrated that, reacted with 3,4,5-trimethoxybenzoic acid chloride, provides N-(4-Hydroxybenzyl)-3,4,5-trimethoxybenzamide. The latter is per se a novel compound and is also the subject of the invention. This compound is reacted with sodium hydride and N,N-dimethylamino ethyl chloride to provide base trimethobenzamide, the latter being salified with hydrochloric acid.
