Reaction Conditions

Reaction Steps

To a solution of 2-(2,4-dichlorophenyl)-2-(trimethylsilyloxy)acetonitrile (1.57 g, 5.73 mmol) in dichloromethane (20 ml) under argon at −78° C. was added (diethylamino)sulfur trifluoride (1.51 ml, 11.5 mmol) dropwise over 15 minutes. The reaction was stirred at this temperature for 20 minutes, then warmed to 0° C. and allowed to stir for an additional 30 minutes. The reaction was poured onto a mixture of ice water and saturated sodium bicarbonate and allowed to stir for 30 minutes. The mixture was extracted with ether twice, and the combined organic layers were washed with saturated sodium chloride, dried over anhydrous magnesium sulfate, filtered, and concentrated to yield 1.05 g of the title compound (89% yield).
