Procedure

A mixture of pyridin-2-amine (6.6 g, 20.0 mmol) in DCM (15 mL) was stirred at room temperature, and O-(mesitylsulfonyl)hydroxylamine (1.0 g, 10.0 mmol) was added slowly. The reaction mixture was stirred at room temperature for 12 h, and the solvent was removed under vacuum. The crude product was used for next step without further purification. ESI MS: m/z 110 [M+H]+.
