Reaction Steps

A solution of N-(methoxymethyl)-N-(phenylmethyl)-N-(trimethylsilyl)methylamine (10.25 g, 43 mmol) in CH2Cl2 (55 mL) was added dropwise, over a 30 minutes period, to a stirred solution of (E)-3-(3,4-dichloro-phenyl)-acrylnitrile (5.70 g, 29 mmol) and trifluoroacetic acid (0.22 mL, 3 mmol) in CH2Cl2 (10 mL) at 0° C. The ice bath was removed, and the solution was stirred at 25° C. for an additional 48 h. It was then concentrated and purification by flash chromatography (SiO2, CH2Cl2) afforded the title compound (7.0 g, 73%) as a colorless oil. ES-MS m/e: 332.3 (M+H+).
