Reaction Steps

2-chloro-4-(trifluoromethyl)benzaldehyde (400 mg, 1.92 mmol) was diluted with nitromethane (727 μl, 13.4 mmol) followed by the addition of methylamine hydrochloride (77.7 mg, 1.15 mmol) and sodium acetate (94.4 mg, 1.15 mmol). After stirring for 12 hours, the reaction was loaded directly onto a biotage 25 cartridge and eluted with 5% ethyl acetate/hexanes to 50% ethyl acetate/hexanes to yield (E)-2-chloro-1-(2-nitrovinyl)-4-(trifluoromethyl)benzene (160 mg, 0.636 mmol, 33.2% yield).
