To a solution of the compound of Example 25 (0.125 g, 0.178 mmol) and methyl sulfide (0.405 mL, 5.48 mmol) in acetonitrile (0.75 mL) at 0° C. was added benzoyl peroxide (0.63 g, 2.60 mmol), and the mixture was stirred at 0° C. for 1 hour. 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 (0.104 g, 77% yield).
