HCID 11063309HCID 11063309, compound

Procedure

The procedure was similar to that in Example 1 by reacting n-octanal with cyclopentanone in the presence of 1% NaOH to give 2-(E)-octylidene cyclopentanone. The boiling point of this intermediate compound was determined to be 120°-125° C. at a pressure of 4 mm Hg. A subsequent Mannich reaction yielded the 2-Dimethylaminomethyl-5-(E)-octylidene cyclopentanone hydrochloride. The melting point of the product was determined to be 138°-140° C.
