Tetrahydrofuran → N-(2-Bromo-5-iodopyridin-4-yl)methanesulfonamide

Participants

Reaction Steps

N-(2-Bromo-5-iodopyridin-4-yl)-N-(methylsulfonyl)methanesulfonamide (7) (228 mg, 0.50 mmol) was stirred with THF (1.3 ml) and 10% sodium hydroxide in water (1.3 mL) at r.t. for 3 hours. The THF was evaporated and the aqueous was neutralised using 10% citric acid solution. The deposited white solid was filtered off and washed with water, then dried in a vacuum desiccator over sodium hydroxide to give the title compound (159 mg 84%). 1H-NMR (d6-DMSO, 500 MHz): δ 3.29 (s, 3H), 7.54 (s, 1H), 8.64 (s, 1H)
