Reaction Steps

A mixture of methyl (4-chloro-3-(1-methyl-1,2,3,6-tetrahydropyridin-4-yl)-5-nitrophenyl)carbamate (213 mg, 0.654 mmol) and platinum (IV) oxide (240 mg, 0.654 mmol) in a mixture of MeOH (50 mL) and ethyl acetate (3 mL) was hydrogenated (balloon of H2). The reaction completed within 1 h. The catalyst was removed by filtration through a celite pad and the pad was rinsed with MeOH. The solvent was removed and radial silica gel chromatography, eluting with DCM containing 0 to 3% MeOH gave methyl (3-amino-4-chloro-5-(1-methylpiperidin-4-yl)phenyl)carbamate (131 mg) as a white solid.
