실험 절차

Stir 32.7 g of 2-methoxypyrroline, 63.8 g of 4-phenylbenzylcyanide and 5 g of 1,5-diazabicyclo[5,4,0]undec-5-ene for 26 hours at 110°. After cooling, take up the mixture with 500 ml of diethyl ether. Filter the formed precipitate and recrystallize it from 400 ml of ethanol with activated charcoal to obtain 12.2 g (14% of theory) of the title compound (m.p. 168° to 170°).
