Participants

Reaction Steps

A solution of N-(3-chloro-4-fluorophenyl)-4-(hydroxymethyl)-1,2,5-oxadiazole-3-carboxamide (8.50 g, 31.3 mmol) and Dess-Martin periodinane (14.6 g, 34.4 mmol) in DCM (400 mL) was stirred at 25° C. for 3 h. The reaction was diluted with saturated sodium bicarbonate solution and extracted with ethyl acetate three times, dried with sodium sulfate, filtered, and concentrated in vacuo. The crude residue was purified by flash column chromatography to yield the desired product (7.50 g, 89%). LCMS for C10H6ClFN3O3(M+H)+: m/z=270.0.
