Reaction Steps

To a mixture of 1-(1H-pyrrolo[3,2-c]pyridin-4-yl)ethanone (680 mg, 4.25 mmol) in anhydrous THF (40 mL) at 0° C. was added NaH (60% in mineral oil, 204 mg, 5.1 mmol). After the mixture was stirred at 0° C. for 30 min, 4-methylbenzene-1-sulfonyl chloride (850 mg, 4.46 mmol) was added. The reaction mixture was stirred at 0° C. for 1 h. The reaction mixture was poured into water (150 mL), extracted with EtOAc (3×50 mL) and concentrated under reduced pressure to afford 1.32 g (98.9%) of 1-(1-tosyl-1H-pyrrolo[3,2-c]pyridin-4-yl)ethanone as yellow solid: MS (ESI) m/z: 315.2 [M+1]+.
