• 3,4-Dimethoxybenzamide (1a) and N-methyl-3,4-dimethoxybenzamide (1b) were prepared from ammonia or methylamine and 3,4-dimethoxy-benzoic acid via the corresponding acyl chloride. 3,4-Di-methoxyphenylacetamide (3a) and N-methyl-3,4-dimethoxyphenylacetamide (3b) were obtained in a similar way from 3,4-dimethoxyphenylacetic acid
