Procedure
To a stirred solution of benzyl 4-[(methoxycarbonyl)amino]-1H-pyrrolo[3,2-c]pyridine-1-carboxylate (264 mg, 0.82 mmol, Step a) in ethanol (10 mL) was added catalytic amount of palladium on carbon (10% wet). The reaction mixture was stirred under an atmosphere of hydrogen gas (atmospheric pressure) for 1 hour. The reaction mixture was filtered over celite and the residue washed with ethanol. The filtrate was concentrated to yield methyl 1H-pyrrolo[3,2-c]pyridin-4-ylcarbamate as a white powder (141 mg, 90.75%).
