2-Substituted 3-amino-3-(methylthio)acrylonitriles cyanoketene S,N-acetals are synthesized by two convenient methods. The imino esters of their hydrochloride salts are found to be good starting materials for the synthesis of 4-substituted 3,5-diaminopyrazoles and 2,5-disubstituted 1,3,4-oxadiazoles.
