Provided is a novel method whereby an amide compound can be produced by highly stereoselectively and efficiently performing amidation between a plurality of amino acids and/or peptides. A compound of general formula (3) is synthesized by forming an amide bond between the carboxyl group on the right side of general formula (1) in a compound represented thereby and the amino group on the left side of general formula (2) in a compound represented thereby, in the presence of a Lewis acid catalyst and a silylating agent [in formulae (1), (2) and (3), each symbol has the same meaning as defined in claims]. ##STR00001##
