Magnesium 2-(dioxidan-2-ide-1-carbonyl)benzoate--water (1/1/6) → 8-(Cyclopropylmethyl)-3-[3-methoxy-4-(2-methyl-1,3-oxazol-5-yl)phenyl]-8-[4-(methylsulfonyl)phenyl]-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyridine

Participants

Reaction Steps

To a mixture of 8-(cyclopropylmethyl)-3-[3-methoxy-4-(2-methyl-1,3-oxazol-5-yl)phenyl]-8-[4-(methylsulfanyl)phenyl]-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyridine (86.0 mg) in DMF (1 mL) was added monoperoxyphthalic acid magnesium salt hexahydrate (87.4 mg) at 0° C., and the mixture was stirred at room temperature for 2 hr. Monoperoxyphthalic acid magnesium salt hexahydrate (87.4 mg) was added to the reaction mixture at room temperature, and the mixture was stirred at room temperature for 2 hr. The reaction mixture was diluted with ethyl acetate, the mixture was washed with aqueous sodium thiosulfate solution (1M) and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate) to give the title compound (27.8 mg).
