실험 절차

To a slurry of the compound of Example 2D (2.00 g, 2.84 mmol) and ethyl sulfide (8.0 mL, 74.06 mmol) in acetonitrile (28.0 mL) at room temperature was added benzoyl peroxide (4.95 g, 20.45 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 (2.35 g, 84% yield).
