Reaction Steps

To a solution (3 mL) of 5-{2-cyclopentyl-1-[4-(methylsulfonyl)phenyl]ethyl}-3-methyl-1H-pyrrole-2-carbothioamide (120 mg) in N,N-dimethylacetamide was added 2-bromo-1,1-diethoxyethane (125 mg), and the mixture was stirred at 60° C. for 2 hr, then at 100° C. for 4 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 (60 mg, yield 47%) was obtained as colorless amorphous crystals from a fraction eluted with ethyl acetate-hexane (1:1, volume ratio). MS: 415 (MH+).
