Participants

Reaction Steps

m-Chloroperoxybenzoic acid (75%, 545 mg, 2.36 mmol) was added to a solution of 4-[4-(4-azidomethyl-[1,2,3]triazol-1-yl)-2,6-difluoro-phenyl]-thiomorpholine (800 mg, 2.36 mmol), obtained in Example 13, in dichloromethane (10 mL) at 0° C. and allowed to stir for 1 h. The reaction mixture was then diluted with dichloromethane (20 mL) and a solution of sodium sulfite was added. Aqueous layer was separated and the dichloromethane layer was washed with water followed by brine and dried over sodium sulfate. Removal of volatiles produced the title sulfoxide (800 mg, 95%).
