This method can be used for the efficient and practical synthesis of various N-substituted formamides without the use of unmanageable cyano compounds. A facile and versatile method for preparing N-substituted amidesfrom alcohols and amides using a Brønsted acid and an alkali metal halide has been developed. Treatment of tertiary alcohols and amides in the presence of an alkali metal halide or methanesulfonic
demonstrated by the synthesis of an intermediate of a bioactive compound on a large scale. A facile and widely applicable method for the synthesis of N-substituted amidesfrom alkenes and amides using Brønsted acids was developed. Treatment of various alkenes with amides and an alkali metal halide or methanesulfonic acid in trifluoroacetic acid afforded the corresponding N-substituted amides in good to high
