実験手順

To a stirred suspension of N-(5-chloropyridin-2-yl)-2-[(piperidin-4-ylcarbonyl)amino]benzamide trifluoroacetate (0.4 g, 0.85 mmol) in acetone (6 mL) and 1,2-dichloroethane (10 mL) was added glacial acetic acid (0.2 mL, 3.84 mmol) followed by then sodium triacetoxyborohydride (0.81 g, 3.84 mmol). After stirring for 15 h, saturated aqueous ammonium chloride (10 mL) was added. After stirring for 0.5 h, the mixture was partitioned between dichloromethane and water and the layers separated. The organic phase was washed with saturated aqueous sodium chloride, dried with magnesium sulfate, filtered, and concentrated in vacuo. The residue was then purified by preparative RPHPLC (C18), eluting with a linear gradient of 90/10 to 60/40 (0.01% HCl/acetonitrile) over 180 min. The product containing fractions were combined and lyophilized to give 0.212 g (57%) of the title compound as a white solid.
