실험 절차

To 2-fluoro-6-[(6-trifluoromethyl-pyridin-3-ylmethyl)-amino]-nicotinic acid methyl ester (562, 1.40 g, 4.25 mmol) in tetrahydrofuran (100.0 mL) under an atmosphere of nitrogen at room temperature, a solution of lithium tetrahydroaluminate (1.00 M in tetrahydrofuran, 10.0 mL) was added slowly. The reaction was stirred at room temperature overnight, followed by addition of an appropriate amount of sodium sulfate decahydrate. After 1 hour, the reaction mixture was filtered and concentrated to give crude compound (563, 1.2 g, 93.7%) that was used in the next step without further purification.
