Reaction Steps
A suspension of methyl 2-bromo-3-cyclohexyl-1-phenylsulfanylmethyl-1H-indole-6-carboxylate (1.10 g, 2.41 mmol), potassium acetate (260 mg, 2.64 mmol) and tetrakis(triphenylphosphine) palladium (279 mg, 0.24 mmol) in N,N-dimethylacetamide (30 ml) was stirred at 100° C. for 3 hr. The reaction mixture was allowed to cool to room temperature, 2N hydrochloric acid was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was successively washed with water and saturated brine and dried over anhydrous sodium sulfate. After filtration, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (hexane:ethyl acetate=20:1-7:1) to give methyl 11-cyclohexyl-5-thia-6a-azabenzo[a]fluorene-8-carboxylate (100 mg, yield 11.0%).
