2-(Benzenesulfonyl)-3-phenyloxaziridine → 5-Methanesulfinyl-2-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-pyridine

참여 물질

반응 단계

To a solution of 2-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-5-methylsulfanyl-pyridine (70 mg, 0.22 mmol) in dichloromethane (2.1 mL) was added 2-benzenesulfonyl-3-phenyl-oxaziridine (58.5 mg, 0.22 mmol) and the reaction mixture was stirred overnight at room temperature. The mixture was then evaporated. Purification by chromatography (SiO2, heptane:ethyl acetate 8:2 to 1:3) afforded the title compound (70 mg, 95%) as a white solid. MS: m/e=329.2 [M+H]+.
