Reaction Steps

The procedure was similar to that in Example 4 by reacting benzaldehyde with the morpholine enamine of cyclopentanone to give 2-(E)-benzylidene cyclopentanone. The melting point of this intermediate compound was determined to be 67°-69° C. A subsequent Mannich reaction yielded the 2-Dimethylaminomethyl-5-(E)-benzylidene cyclopentanone hydrochloride. The melting point of the product was determined to be 153°-155° C.
