Procedure
A mixture of 4,4'-methylene dianiline (198 g; 1 mole), acetophenone (240 g; 2 moles) and a catalytic amount of stannous chloride was refluxed in toluene (3L) for 30 hours using a Dean-Stark trap. The theoretical amount of water was removed from the system. The toluene was then removed under vacuum.
