実験手順

Add 4-dimethylamino-pyridine (0.19 g, 1.5 mmol), triethylamine (3.2 mL, 23.2 mmol), and 3-(2-chloro-6-fluoro-phenyl)-5-methyl-isoxazole-4-carbonyl chloride (5.53 g, 20.1 mmol) to a solution of 3-amino-piperidine-1-carboxylic acid methyl ester (2.45 g, 15.5 mmol) in dichloromethane (100 mL). Stir the reaction at room temperature under nitrogen overnight. Wash the reaction with 1N HCl, saturated aqueous sodium bicarbonate solution, and brine; dry over magnesium sulfate; and concentrate. Purify by flash chromatography on silica gel (eluting with 0.75% methanol/chloroform) to give 5.49 g of the title compound as a yellow foam, 90% yield. 1H NMR: consistent with structure. MS (ion spray) 396 (M+).
