Procedure

To a solution of 44 (1.24 g, 2.04 mmol) in 25 mL of CH2Cl2 at -78° C. is added a solution of 64% m-CPBA (550 mg, 2.04 mmol) in 10 mL of CH2Cl2. The reaction mixture is allowed to warm to -15° C., quenched with methyl sulfide (2.07 mL, 1.75 g, 6.8 mmol) and warmed to room temperature. The reaction mixture is then diluted with 25 mL CH2Cl2, washed with saturated NaHCO3 (50 mL), H2O (50 mL), saturated NaCl (50 mL), dried over Na2SO4, filtered, concentrated and purified by flash chromatography (30% EtOAc/hexane) to afford 1.14 g (89%) of the title compound 45 as a mixture of diastereomers: Rf 0.14 and 0.28 (10% EtOAc/hexane).
