Procedure

To a solution of 5-bromo-2-(5-{1-[4-(cyclopropylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrol-2-yl)pyridine (200 mg) in N,N-dimethylformamide (1 mL) were added ethyl sulfanylacetate (98 μL) and tetrakistriphenylphosphinepalladium(0) (230 mg), and the mixture was stirred using a microwave synthesis apparatus at 120° C. for 3 hr. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate and washed with water. The ethyl acetate layer was washed with saturated brine, dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and the title compound (117 mg, yield 54%) was obtained as a yellow amorphous solid from a fraction eluted with ethyl acetate-hexane (3:2, volume ratio). MS: 555 (MH+).
