A series of ethyl 2-aminomethyl-3, 3-di(2-thienyl)acrylates were prepared. These compounds were planned to agree with general rule for analgesics and to possess combined characteristics of dithienylaminobutene compounds and pethidine hydrochloride. However, their analgesic and antitussive actions were not as strong as were expected but were stronger than that of ethyl 2-aminomethyl-3, 3-diphenylacrylates.
