Reaction Steps
1-(2-Chloropyridin-3-yl)propan-1-one (600 mg) and [4-(benzyloxy)phenyl]hydrazine hydrochloride (976 mg) were dissolved in ethanol (10 ml), and the mixture was stirred under microwave irradiation at 170° C. for 3 hr, and concentrated. The residue was purified by basic silica gel column chromatography (hexane/ethyl acetate) to give the title compound (300 mg). MS (API+): [M+H]+ 330.1.
