Reaction Steps
A suspension of 2-chloronicotinaldehyde (228 mg, 1.62 mmol) and sodium 6-(4-fluorophenyl)naphthalene-2-sulfinate (500 mg, 1.62 mmol) in DMSO (2.5 mL) was heated for 12 hours at 80° C. The reaction was poured into water (10 mL) and extracted with ethyl acetate (3×10 mL). The combined organic layers were washed with water and brine, dried (Na2SO4) and evaporated in vacuo. The residue was purified by flash column chromatography on silica, eluting with 35-60% ethyl acetate/isohexane, to give the title compound as solid (349 mg). 1H NMR (400 MHz, d6-DMSO): δ 11.00 (1H, s), 8.84-8.82 (2H, m), 8.40-8.34 (3H, m), 8.25 (1H, d, J=8.7 Hz), 8.06-8.02 (2H, m), 7.94-7.84 (3H, m), 7.38 (2H, t, J=8.8 Hz).
