실험 절차

A solution of 6-methoxy-α-methyl-2-naphthylacetic acid (3.5 g, 0.015 mol), triethylamine (4.3 ml, 0.03 mol), 4-(3-trifluoromethylphenyl)-1,2,3,6-tetrahydropyridine hydrochloride (3.9 g, 0.015 mol), and benzotriazolyl-N-oxytris(dimethylamino)phosphonium hexafluorophosphate (BOP) (6 g, 0.015 mol) in methylene chloride (40 ml) is stirred at room temperature for 4 hours. Ethyl acetate (150 ml) is then added thereto and the mixture is washed in sequence with water, 10% NaHCO3, water, 1N HCl, and water. The reaction mixture is then filtered over silica and concentrated to dryness affording 1-[4-(3-trifluoromethylphenyl)-1,2,3,6-tetrahydropyrid-1-yl]-1-oxo-2-(6-methoxy-naphth-2-yl)propane (4 g) as a thick oil.
