Procedure
Following the procedure of example 1B, 13.8 g (0.0645 mol) of 2-(4-fluorophenyl)-1-phenylethanone was reacted with 20 mL of dimethyl formamide dimethyl acetal to yield 13.6 g of 3-(dimethylamino)-2-(4-fluorophenyl)-1-phenyl-2-propen-1-one, mp 115°-116° from isopropyl acetate. The enamine (10.5 g, 0.039 mol) was reacted with 6.03 g (0.039 mol) of ethyl hydrazinoacetate hydrochloride to yield 12.1 g of product mp 86°-87° C. from methyl-t-butyl ether.
