Reaction Steps

2-(4-{[(3,4-Dichloro-5-methyl-1H-pyrrol-2-yl)carbonyl]amino}piperidin-1-yl)-N-methoxy-6-(methylsulfinyl)isonicotinamide (Example 152) (90 mg, 0.185 mmol) was dissolved in anhydrous DCM (5 ml). mCPBA (32 mg, 0185 mmol) was added and the mixture was stirred at room temperature for 12 h. The crude mixture was diluted and washed with 10% sodium thiosulfate, water, brine and dried over sodium sulfate and concentrated in vacuo. The brown oil was purified by flash chromatography eluting with acetonitrile/water (0.1% TFA) to give the title compound (11 mg).
