Potassium Hydroxide → HCID 59278253, compound

Participants

Reaction Steps

To a stirred solution of (1H-pyrrolo[2,3-b]pyridin-4-ylmethyl)-carbamic acid tert-butyl ester (400 mg, 1.62 mmol) in DMF (10.0 mL) was added powdered KOH (143 mg, 1.88 mmol). After 15 minutes, methanesulfonyl chloride (137 μL, 1.78 mmol) was added. After 15 hours, the mixture was diluted with water (30 mL) and extracted with ethyl acetate (3×50 mL). The combined organic layers were washed with brine (25 mL), dried over magnesium sulfate, filtered and concentrated. The residue was purified by silica gel chromatography eluting with a gradient of 0-50% ethyl acetate in heptane to afford (1-methanesulfonyl-1H-pyrrolo[2,3-b]pyridin-4-ylmethyl)-carbamic acid tert-butyl ester.
