A mixture of 90.15 g of ethylenediamine, 50.7 g of benzhydryl chloride and 300 ml of acetonitrile is heated under reflux for 24 hours. It is partitioned between 400 ml of diethyl ether and 175 ml of 10% sodium hydroxide solution, the ether phase is separated off, dried over magnesium sulphate, evaporated to dryness and distilled under reduced pressure. N-diphenylmethylethylenediamine is obtained, b.p.0.13 =116°-124° C., m.p. 23°-24° C.
