Versuchsvorschrift

30 grams of ethyl nicotinate and 80 grams of 2-benzylthio ethylamine are heated for 12 hours at 170°-180° C. The ethane liberated during the reaction is removed by means of a Dean Stark apparatus. After cooling, the reaction mixture is dissolved in 400 cc of carbon tetrachloride; by addition of petroleum ether, the N-(2-benzylthioethyl)nicotinamide crystallizes: 47 g. By crystallization in a mixture of carbon tetrachloride and cyclohexane, there are recovered colorless crystals of the above product melting at 79° C.
