Procedure
21.7 g of ethyl 2-cyano-3,3-bis(methylthio)acrylate and 16.5 g of 4-(N,N-diethylamino)aniline are heated for 2 hours at 120° C. The residue is purified by chromatography on a silica column, the eluent being a toluene/ethanol (97/3) mixture; the expected product is recrystallised from cyclohexane. M.p.=100° C. (Yield 81%).
