Participants

Reaction Steps

A solution of 1-(2-(4-fluorophenyl)thiazol-5-yl)ethanol (1.0 g, 4.4 mmol) in dichloromethane (40 mL) was cooled to 0° C. Dess-Martin periodinane (5.7 g, 13.4 mmol) was added slowly at 0° C. and the reaction mixture stirred at room temperature for 2 h. The reaction mixture was quenched with saturated NaHCO3 solution (80 mL), sodium thiosulfate solution (20 mL), extracted with ether (2×1000 mL), the organic layer dried over Na2SO4, filtered and concentrated to obtain crude product. The crude product was purified by Combiflash® chromatography (40% ethyl acetate in hexane) to afford 1-(2-(4-fluorophenyl)thiazol-5-yl)ethanone as off-white solid (820 mg, 83% yield). 1H NMR (400 MHz, DMSO-d6): δ 8.67 (s, 1H), 8.08 (t, 2H), 7.37 (t, 2H), 2.59 (s, 3H); LC-MS m/z calculated for [M+H]+222.03. found 222.3.
