Reaction Steps

A solution of (4-bromo-2,6-dichlorophenyl)(1H-pyrrolo[3,2-c]pyridin-1-yl)methanone (100 mg, 0.27 mmol) and ethyl acrylate (3.06 mL, 30.58 mmol) in dimethylformamide (3 mL) was stirred at room temperature. Triethylamine (0.15 mL, 1.08 mmol) was added followed by triphenylphosphine (42.6 mg, 0.16 mmol) and palladium acetate (18.16 mg, 0.008 mmol). The reaction mixture was purged with argon and heated under reflux for about 20 hours. The reaction mixture was cooled to room temperature and the residue was poured into water and extracted with ethyl acetate. The combined organic layer was dried over anhydrous sodium sulfate, filtered and the solvent was removed under rotary evaporator. Ethyl (2E)-3-[3,5-dichloro-4-(1H-pyrrolo[3,2-c]pyridin-1-ylcarbonyl)phenyl]prop-2-enoate (64.8 mg, 61.59%) was isolated by silica gel column chromatography using ethyl acetate in hexane (15-17%) as eluant.
