Reaction Steps

To a mixture of 3-chloro-2-(trifluoromethyl)benzyl methanesulfonate (0.150 g, crude) and trimethylsilanecarbonitrile (119 mg, 1.2 mmol) in acetonitrile (5 mL) was added a solution of tetrabutylammonium fluoride in THF (1M, 1.2 mL, 1.2 mmol). The reaction was stirred at room temperature for 2 h. The reaction was treated with ethyl acetate and water, and the separated organic layer was washed with brine, dried and concentrated to give the crude product, which was purified by silica gel column chromatography (10% ethyl acetate in petroleum ether) to afford the title compound (0.10 g, 3.03 mmol, 68% yield over three steps) as a yellow solid. 1H NMR (400 MHz, CDCl3) δ (ppm) 7.56-7.48 (m, 3H), 3.99 (d, J=2.0 Hz, 2H).
