Procedure

To a 25° C. mixture of sulfonamide (60) (185 mg, 0.4 mmol) in THF (10 mL) was added isobutyryl chloride (107 mg, 1 mmol) and triethyl amine (607 mg, 6 mmol). The mixture was stirred for 18 hours, followed by filtration to remove the solid. The filtrate was concentrated in vacuo and purified via chromatography, to afford the title compound as white solid (17 mg).
