Agitate a mixture of 5.0 g of 4-chlorobenzyl cyanide, 5.5 g of caprolactim methyl ether and 0.5 g of diazabicyclo [5.4.0]undec-5-ene under nitrogen for 18 hours at 125°. Cool the thus-obtained reaction mixture to ambient temperature and then rub down the crystallizing residue with 20 ml of methyl alcohol before filtering to obtain 5.5 g of the title compound. Recrystallize this compound from methyl alcohol to obtain a product with a MP of 114° to 117°.
