反应详情

Sodium borohydride (0.117 g, 3.08 mmol) was added to a solution of 2-{[4-(trifluoromethyl)pyridin-2-yl]methyl}cyclopentan-1-one (0.375 g, 1.54 mmol) in ethanol (10 ml). The reaction was stirred at room temperature for 3 hours and then quenched with water (5 mL) and 2M HCl (aq., 5 ml). The organics were extracted with ethyl acetate (2×30 ml) and the combined organics were washed with brine (10 ml), dried over magnesium sulfate, filtered through a hydrophobic frit and concentrated in vacuo. The crude product was purified by column chromatography (silica, 0-35% ethyl acetate/petrol) to afford the title compound as two diastereomers.
