Reaction Steps

A mixture of NaH (4.0 g, 99 mmol) in 50 mL NMP stirred at 0° C., was treated dropwise with a mixture of bromoethane (11 g, 99 mmol) and 2-(4-chlorophenyl)acetonitrile (15 g, 99 mmol) in 20 mL ether. The mixture was stirred at room temperature for 2 hours, cooled to 0° C., and quenched carefully with H2O. The resulting mixture was neutralized with 10% HCl to a pH of 5. The mixture was extracted with ether (3×50 mL). The combined organic layers were washed with brine (30 mL), dried over anhydrous Na2SO4, concentrated in vacuo, and purified by column chromatography eluting with 5% EtOAc/hexane to give 9.1 g of the product as a pale yellow oil.
