Diethyl Ether → HCID 20153940, compound

Participants

Reaction Steps

124.1 g (0.5 mol) of 4,4'-methylene-bis-(phenylcyanamide) and 510.5 g (1.0 mol+400% excess) of acetic anhydride are reacted at 73°-83° C. for 4 hours and 10 minutes, 465 ml of diethyl ether are then added and the mixture is cooled. The suspension is filtered with suction and the residue is dried at 50° C. in vacuo to give 139.6 g (84.0% of theory) of a crystalline product which, after recrystallisation from toluene, has a melting point of 134°-136° C.
