Reaction Steps

A mixture of the product from Example 58 (0.0200 g, 0.047 mmol) and 3-chlorobenzoperoxoic acid (0.0125 g, 0.051 mmol) in DCM (0.5 mL) was stirred at room temperature for 1 hour, diluted with EtOAc, washed with sat NaHCO3 and brine, dried (Na2SO4), filtered, and chromatographed (8-10% EtOAc/DCM) to give 4.5 mg of the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 11.90 (s, 1H), 8.44-8.48 (m, 1H), 8.30-8.34 (m, 1H), 7.86-7.96 (m, 2H), 7.70-7.76 (m, 2H), 7.50-7.61 (m, 3H), 7.38-7.46 (m, 4H), 3.76 (s, 2H); MS (ESI−) M/Z 436 (M−H)−.
