YieldReaction ConditionsOperation in experiment
In water; at 0 - 20℃; Step 2. 5-bromo-A/-methyl-3-pyridinesulfonamideTo CH3NH2 (50 mL of a 23-30 weight percent in H20) at 0 °C, was added 5-bromo- 3-pyridinesulfonyl chloride (44 mmol). The mixture was then warmed to rt and stirred for 3 h. The mixture was then extracted with EtOAc and concentrated in vacuo. The crude material was combined with that from an additional experiment (10 mmol scale) run under identical conditions and washed with 10:1 hot petroleum ether/EtOAc to afford 5-bromo-/V- methyl-3-pyridinesulfonamide (2.4 g, 18percent combined yield over two steps).
