Potassium Carbonate → {5-Cyclopropyl-6-[(4-methoxybenzyl)oxy]pyridin-2-yl}[4-(cyclopropylsulfonyl)phenyl]methanol

Participants

Reaction Steps

A solution of {5-cyclopropyl-6-[(4-methoxybenzyl)oxy]pyridin-2-yl}[4-(cyclopropylsulfanyl)phenyl]methanol (469 mg) in chloroform (15 mL) was stirred in an ice bath, and m-chloroperbenzoic acid (560 mg) was added as powder. The mixture was returned to room temperature and stirred for 3.5 hours. The reaction solution was stirred again in an ice bath, and sodium thiosulfate and a potassium carbonate solution were added, followed by extraction with chloroform. The organic layer was dried over anhydrous magnesium sulfate and filtered. The filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=92:8→34:66) to give {5-cyclopropyl-6-[(4-methoxybenzyl)oxy]pyridin-2-yl}[4-(cyclopropylsulfonyl)phenyl]methanol as a light yellow oil (403 mg, 80%).
