Process for the preparation of N-butyryl-4-amino-3-methyl-benzoic acid methyl ester and the new compound N- (4-bromo-2-methylphenyl) butanamide
According to the invention, N-butyryl-4-amino-3-methyl-methyl benzoate is obtained in a particularly advantageous manner by, initially, reacting o-toluidine with butyric acid chloride, by brominating the reaction product and by reacting the bromide obtained therefrom with carbon monoxide and methanol in the presence of a palladium catalyst. The invention also relates to the important novel chemical compound N-(4-bromine-2-methylphenyl)-butanamide.
