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

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
