m-Chloroperbenzoic acid → HCID 22458972, compound

Participants

Reaction Steps

The product of Example 63, Step H (2.017 grams) in CH2Cl2 solution (40 mL) was stirred (0° C.) and treated with solid 75% m-chloroperbenzoic acid (1.567 grams) in portions. The reaction was warmed to ambient temperature after 15 minutes and stirred for 1.5 hours. Partition of the reaction between isopropyl acetate and aqueous sodium bicarbonate was followed by washing of the organic with aqueous sodium bicarbonate, then water. Drying over magnesium sulfate, filtration and evaporation afforded a solid which was chromatographed over silica gel (2 step gradient; 5:1 hex/ethyl acetate; 5:2 hex/ethyl acetate; 5:2:0.35 hex/ethyl acetate/methanol). The title compound was acquired as a white solid.
