Reaction Conditions

Reaction Steps

A 25 ml pressure tube was charged with 1-(4-methyl-1-phenylpent-1-yn-3-yl)piperidin-4-one (76.6 mg, 0.30 mmol) and ammonium chloride (48 mg, 0.90 mmol). The pressure tube was purged with argon for 5 min and then saturated ethanolic ammonia solution (2 ml) was added. The pressure tube was sealed tightly and the reaction mixture was stirred at 90° C. for 4 hrs. The reaction mixture was concentrated under reduced pressure and the brown residue was subjected to flash chromatography on silica gel (EtOAc/MeOH=19:1) to give 33.3 mg of a pure title compound as a yellowish oil. (yield: 64%)
