tert-Butyl [2-(6-acetyl-4-chloro-2-formyl-3-methylphenoxy)ethyl]carbamate (85 mg, 0.24 mmol) was stirred in methanol (7 mL) and 1.0 M sodium hydroxide in water (2.7 mL) and urea hydrogen peroxide addition compound (200 mg, 2 mmol) was added. Additional urea hydrogen peroxide addition compound (20 mg) and 1.0 M sodium hydroxide in water (0.5 mL) were added and the mixture was stirred for 3 more hours. 1 N HCl was added to pH 5 and the methanol was evaporated. The mixture was extracted with ethyl acetate, washed with brine, dried over sodium sulfate, filtered and evaporated to give the desired compound (75 mg, 84%). LCMS calculated for C17H22ClNO6Na (M+Na)+: m/z=394.1; found: 393.9.
