Procedure
A mixture of 7.4 g. of 3,5-bis(dimethylamino)-α-[(methylsulfonyl)methyl]4-piperidinobenzyl alcohol, 1.64 g. of sodium methylate and 4.4 g. of β-anilinopropionitrile in 40 ml. of dimethylsulfoxide was stirred for 2 hours at 50° C. under nitrogen. The mixture was poured into 250 ml. of water, the precipitated product extracted with ethyl acetate, the ethyl acetate solution dried over sodium sulfate and evaporated. By purification of the residue over aluminum oxide with benzene and recrystallization from ethyl acetate/petroleum ether, there was obtained α-(anilinomethylene)-3,5-bis(dimethylamino)-4-piperidinohydrocinnamonitrile having a melting point of 200°-202° C.
