Reaction Steps

A solution of N-(methoxymethyl)-N-(phenylmethyl)-N-(trimethylsilyl)methylamine (9.69 g, 41 mmol) in CH2Cl2 (40 ml) was added drop wise, over a 30 minutes period, to a stirred solution of 1-chloro-3-((E)-2-nitro-vinyl)-benzene (0.68 g, 3.37 mmol) and trifluoroacetic acid (0.21 ml) in CH2Cl2 (40 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, EtOAc/H 1:4) afforded 6.30 g (73%) of the title compound as a colorless oil. ES-MS m/e: 317.1 (M+H+).
