反応手順

7-[(4′-Trifluoromethyl-biphenyl-2-carbonyl)-amino]-quinoline-3-carboxylic acid (40 mg, 0.092 mmol) was combined with 4-methylbenzylamine (17 mg, 0.14 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (21 mg, 0.11 mmol), 1-hydroxybenzotriazole (14 mg, 0.10 mmol), and triethylamine (0.051 ml, 0.37 mmol) in 1.5 ml of dichloromethane. After stirring overnight at ambient temperature, the reaction mixture was diluted with 50 ml of dichloromethane, and the organic phase washed sequentially with water, and brine, and then dried over anhydrous magnesium sulfate, filtered and concentrated under vacuum to provide a residue. This material was purified by preparative thin-layer-chromatography on silica eluting with 4% methanol in dichloromethane. The product containing band was collected and eluted with 5% methanol in ethyl acetate to afford 20 mg of the title compound as a colorless solid.
