실험 절차

To a solution of N-trifluoroacetyl-7-hydroxy-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine, O-trifluoromethanesulfonate (100 mg, 0.25 mmol) in dimethylformamide (2 mL) was treated with (2-methyl-2H-pyrazol-3-yl)-tri-n-butyltin (138 mg, 0.37 mmol), LiCl (21 mg, 0.50 mmol), Pd(PPh3)2Cl2 (35 mg, 0.05 mmol) and stirred at 100 C for 4 hours. The product mixture was diluted with EtOAc (20 mL), washed twice with water (10 mL), once with brine (10 mL), dried with Na2SO4 and concentrated. Flash chromatography (30% EtOAc in hexane, silica) resulted in 80 mg of a clear oil. MS calculated for C17H18F3N3O+H: 338, observed: 338.
