Reaction Steps

The mixture of 800 mg of 2-chloro-3-(methylsulfonyl)pyridine (synthesized according to a method disclosed in J. Org. Chem. 1979, 44, 3080-3082) and 60 mL of aqueous ammonia, was stirred overnight in a sealed-tube at 175° C. After cooling back to room temperature, the mixture was extracted with diethyl ether, and the organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The insolubles were filtered. The filtrate was concentrated under reduced pressure, and 473 mg of 3-(methylsulfonyl)pyridine-2-amine [162-1] was obtained as a light orange solid.
