Reaction Conditions

Reaction Steps

To a suspension of sodium hydride (0.34 g, 14 mmol) in anhydrous THF (80 mL) was added portionwise N-(diphenylmethylene)aminoacetonitrile (3.13 g, 14 mmol). The reaction was allowed to stir at room temperature until hydrogen evolution ceased and then cooled to 0° C. for 10 minutes. To the reaction mixture was added a solution of methansulfonic acid 2-chloro-pyridinylmethyl ester (3.00 g, 13 mmol) in anhydrous THF (10 mL). The reaction mixture was stirred at room temperature for 20 minutes and then cooled to 0° C. and was added saturated ammonium chloride (50 mL) and extracted with three 100 mL portions of ethyl acetate. The combined organic layers was dried on sodium sulfate and concentrated to give a viscous oil. Purification by column chromatography (40:60 ethyl acetate:hexane) and trituration with hexanes gave 2-(benzhydrylidene-amino)-3-(2-chloro-pyridin-4-yl)-propionitrile (4.02 g, 52%).
