Procedure
To a solution of EXAMPLE 233C (456 mg) and potassium ethanethioate (197 mg) in dioxane (4 mL) was added tris(dibenzylideneacetone)dipalladium(0) (27 mg) and xantphos (33 mg) followed by N,N-diisopropylethylamine (0.5 mL). The mixture was purged with argon, sealed and stirred under microwave irradiation for 60 minutes at 120° C. The mixture was dissolved in ethyl acetate (300 mL) and water (100 mL). The organic phase was washed with brine and dried over Na2SO4. Filtration and evaporation of the solvent followed by flash chromatography (20% ethyl acetate in hexane) provided the title compound.
