Treatment of a series ofpara-substituted aromatic and primary aliphatic carboxamides with NBS and NaOMe in methanol heated to reflux for ten minutes results in the conversion of the carboxamides to their corresponding primary amino methyl carbamates in nearly quantitative yields. The mild oxidative
