반응 단계

To a solution of 5-nitro-2-[(pyrrolidin-1-yl)methyl]benzoxazole (300 mg, 1.21 mmol) in a mixed solvent of EtOAc-MeOH (1:1, 70 mL) was added 10% Pd—C (40 mg), the flask was purged with argon, then the argon was replaced with H2, the reaction mixture was stirred under H2 atmosphere for 30 min. After filtration through Celite, washed with ethyl acetate. The solvents were evaporated to provide 263 mg (100%) of 5-amino-2-[(pyrrolidin-1-yl)methyl]benzoxazole as a yellow solid.
