Participants

Reaction Steps

A mixture of N-cyclopentyl-7-(3,5-dimethylisoxazol-4-yl)quinoxaline-5-sulfonamide (0.069 g, 0.18 mmol) and mCPBA (max 77% by weight, 0.083 g, 0.37 mM) in dichloromethane (3 mL) was stirred at room temperature for 2 hours. Additional mCPBA (0.166 g, 0.74 mM) was added and the reaction stirred for 16 hours at room temperature. Volatiles were removed under reduced pressure and the crude product purified by preparatory HPLC (5-95% MeCN/H2O, 0.1% TFA) to afford the product as a white solid.
