실험 절차

To a solution of 6-(5-aminomethyl-4-chloro-pyridin-3-yl)-1-methyl-3,4-dihydro-1H-quinolin-2-one hydrochloride (example 218, 0.05 g, 0.148 mmol) in dry DMF (1 mL) were added EDCI (0.034 g, 0.077 mmol), hydroxybenzotriazole (0.017 g, 0.077 mmol), Hünig's base (0.057 g, 0.443 mmol) and 3,5-dimethyl-isoxazole-4-carboxylic acid (0.021 g, 0.148 mmol) and the resulting solution was stirred at room temperature for 2 h. The reaction mixture was diluted with EtOAc, poured into sat. NaHCO3 solution (10 mL) and extracted with EtOAc (2×20 mL). Combined organics were dried over Na2SO4, filtered and evaporated to dryness. The residue was purified by silica gel flash chromatography eluting with a 0 to 5% MeOH-DCM gradient to give the title compound (0.03 g, 48%) as a colorless solid. MS: 425.4 (M+H+).
