Reaction Steps

N-benzyl-1-methoxy-N-[(trimethylsilyl)methyl]methanamine was added to a solution of 1-trifluoromethoxy-3-((E)-2-nitro-vinyl)-benzene (6.00 g; 35.90 mmol) in DCM (50 ml). The reaction solution was cooled to 0° C., TFA (0.30 ml; 3.95 mmol) was added dropwise, and stirred overnight at RT. The reaction solution was washed with H2O and brine, dried over MgSO4, filtered, and concentrated. The crude material was purified via Biotage (340 g column) eluting with 5% EtOAc in hexane to provide the desired product 5.5 g, yield 51%.
