5N Sodium hydroxide (320 ul, 1.59 mmol) followed by 50% aqueous hydrogen peroxide (157 ul, 2.55 mmol) were added to solution of N-(1-cyano-4-(4-ethoxy-3-methylphenylsulfonamido)cyclohexyl)acetamide (Intermediate 126, 242 mg, 0.638 mmol) in ethanol (6.4 ml). The reaction was heated to 80° C. for three hours. LCMS indicated approximately 3:1 product:starting material by co-injection. The reaction was diluted with water and extract with four volumes ethyl acetate. The combined organics were dried over sodium sulfate, filtered and concentrate to 226 mg crude. TLC (10% methanol in ethyl acetate): Rf starting material 0.66; major spot Rf=0.25. The crude was chromatographed on Biotage 12M eluting 0-100% ethyl acetate in (10% methanol in ethyl acetate) to give the product as an off-white solid (117 mg, 0.308 mmol). LCMS [M+H]=380.2.
