Procedure

55% Sodium hydride (170 mg) and 4-methylbenzenesulfonyl chloride (740 mg) were added to a solution of 5-bromo-4-iodo-1H-pyrrolo[2,3-b]pyridine obtained by the method described in WO 2008/150914 (1.14 g) in N,N-dimethylformamide (12 ml) in an ice bath, and the mixture was stirred at room temperature for 3 hours. An aqueous ammonium chloride solution was added to the reaction solution, and the precipitated solid was collected by filtration and washed with water. This was dissolved in dichloromethane and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give the title compound (1.68 g).
