Reaction Steps
A suspension of 241 mg (0.34 mmol) of 20% of Pearlman's catalyst on carbon and 693 mg (3.43 mmol) of the 2-methanesulfonyl-5-nitropyridine in 15 mL of MeOH and 3 mL of ethyl acetate was stirred under an atmosphere of hydrogen for 3 hours. The solution was filtered and concentrated. The crude mixture was further purified by filtration through a silica column with ethyl acetate to afford 510 mg (86%) of 6-methanesulfonylpyridin-3-ylamine.
