Procedure

To a solution of the compound of Example 111 (0.200 g, 0.248 mmol) and ethyl sulfide (0.70 mL, 6.48 mmol) in acetonitrile (2.0 mL) at 0° C. was added benzoyl peroxide (0.38 g, 1.57 mmol) in three portions over 2 hours. The reaction was diluted with ethyl acetate and washed with 10% Na2CO3 and brine. The organic was dried over MgSO4, filtered and evaporated. The residue was chromatographed on silica gel eluting with a gradient starting with dichloromethane and ending with ethyl acetate to give the title compound (0.210 g, 95% yield).
