Procedure
A mixture of 3-fluoro-4-(trifluoromethyl)benzaldehyde (0.96 g, 5.0 mmol), 1-(1-isocyanoethylsulfonyl)-4-methylbenzene (1.05 g, 5.00 mmol), and potassium carbonate (0.898 g, 6.50 mmol) was heated to reflux for 2 hours in methanol (25 mL). After this time, the reaction mixture was cooled to room temperature and poured into water, then extracted with ether. Chromatography on silica gel (20 to 40% ethyl acetate-hexane, eluant) afforded the title compound as an off-white solid (1.01 g, 82% yield). 1H NMR (300 MHz, DMSO-d6) δ 8.48 (s, 1H), 7.90 (m, 1H), 7.68 (m, 2H), 2.43 (s, 3H). MS (DCI+) m/z 246 (M+H), 263 (M+NH4).
