A suspension of 5-(2-bromophenyl)-1-(pyridin-3-ylsulfonyl)-1H-pyrrole-3-carbaldehyde (102 mg), zinc cyanide (61.0 mg) and tetrakis(triphenylphosphine)palladium (60.0 mg) in N,N-dimethylformamide (2 mL) was heated (100 W, 4 min 30 sec) using a microwave focused chemical synthesis reactor manufactured by CEM, water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=4:1→2:1) to give the title compound as a pale-yellow oil (yield 97.4 mg, 63%).
