m-Chloroperbenzoic acid → HCID 86634873, compound

Participants

Reaction Steps

Compound 30 (266 mg) was dissolved in anhydrous dichloromethane (50 mL). m-chloroperoxybenzoic acid (266 mg) was added dropwise to the solution under stirring in an ice bath. The mixture was stirred for about 15 minutes under argon which was fed by means of a separately provided balloon filled with argon. The mixture was returned to room temperature, followed by stirring for 3 hours. The reaction mixture was extracted with purified water and chloroform. The organic layer was washed with brine, and the washed organic layer was dried over sodium sulfate anhydrate. The solvent was evaporated to dryness. The residue was purified by silica gel column chromatography (chloroform-methanol), to thereby yield the target product (yield: 265 mg, 94%).
