Participants

Reaction Steps

A vial was charged with 1-(2-allyl-4-(trifluoromethyl)phenyl)-N-(2,4-dimethoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (0.114 g, 0.182 mmol), NMO (0.043 g, 0.364 mmol), t-BuOH (0.607 ml), and water (0.304 ml). Osmium tetroxide (4% aq. soln.) (0.111 ml, 0.018 mmol) was added drop wise and the reaction was stirred for two hours. The reaction was quenched with saturated sodium thiosulfate solution and diluted with ethyl acetate. The aqueous layer was extracted with ethyl acetate, and the combined organic layers were dried with sodium sulfate, filtered, and concentrated. The material was purified via silica gel chromatography (12 g silica gel column, gradient elution 0 to 10% MeOH:DCM) to afford 1-(2-(2,3-dihydroxypropyl)-4-(trifluoromethyl)phenyl)-N-(2,4-dimethoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide as a clear oil. m/z (ESI) 660.3 (M+H)+.
