Reaction Conditions

Temperature120 °C

Reaction Steps

Silver carbonate (28 mg) and acetic acid (0.006 ml) were added to a solution of 4-bromothieno[2,3-c]pyridine-2-carboxylate obtained in the above-described Step 1 (258 mg) in DMF (2.0 ml), and the reaction solution was stirred at 120° C. for 24 hours. The reaction solution was diluted with ethyl acetate and washed successively with an aqueous sodium bicarbonate solution and a saturated saline solution. After drying over anhydrous sodium sulfate, the solvent was evaporated under vacuum. The resultant residue was purified by column chromatography on silica gel (developing solvent:hexane-ethyl acetate) to obtain 4-bromothieno[2,3-c]pyridine.
