Participants

Reaction Steps

Combine 2-nitro-1-(3-trifluoroethoxyphenyl)ethanol (6.1 g, 24.2 mmol) and methanesulfonyl chloride (2.02 mL) in dichloromethane (50 mL) and cool in an ice-bath. Add dropwise, triethylamine (7.28 mL) while maintaining the temperature near 0° C. After 2 hours, pour into ethyl acetate, wash with water, dry with Na2SO4, filter, and then concentrate to residue. Chromatograph the residue on silica gel to give 3-(2-nitrovinyl)-1-trifluoroethoxybenzene: MS (MH+) 234; 1H NMR (CDCl3) 7.97 (1 H, d, J=13.6 Hz), 7.57 (1 H, d, J=13.6 Hz), 7.53-7.48 (2 H, m), 7.40-7.35 (2 H, m).
