反応手順

To a solution of hydrogen peroxide (43 mL) in 250 mL of acetic acid was added methyl isonicotinate. The reaction mixture was stirred at 80° C. overnight (about eighteen hours). The solution was concentrated to about 50 mL, water was added and the mixture was saturated with sodium carbonate. The aqueous phase was extracted with methylene chloride. The organic layer was washed with brine, dried over magnesium sulfate and filtered. The filtrate was concentrated and trituated with hexane. The resulting precipitate was filtered and air-dried to give 24.5 g (65% yield) of product as a white solid: mp: 118-120° C.
