Reaction Steps

4-Chloro-1H-pyrrolo[2,3-b]pyridine-5-carbonitrile (2.6 g, 14.64 mmol) and triethylamine (3.06 mL, 21.96 mmol) in tetrahydrofuran (100 mL) was cooled to 0° C. and benzenesulfonyl chloride (2.253 mL, 17.57 mmol) was added dropwise. The mixture was stirred at 0° C. for 1 hour and at room temperature for 10 hours and the mixture was concentrated. Water was added and the mixture was extracted with dichloromethane (three times). The organic phase was washed with water and brine, dried over sodium sulfate, filtered and concentrated. The residue was triturated with diethyl ether to afford the title compound. MS (ESI(+)) m/e 318 (M+H)+.
