Reaction Steps

To a stirred solution of pyrrolo[2,3-c]pyridin-1-yl-acetic acid benzyl ester (1.0 g, 3.6 mmol) in MeOH (20 mL) in a Parr shaker vessel (250 mL), palladium-charcoal (100 mg) is added under nitrogen atmosphere. Nitrogen is flashed with hydrogen and the solution is hydrogenated at room temperature at 10 psi hydrogen pressure. Reaction is monitored by TLC. After complete consumption of starting material, the reaction mixture is taken out from the Parr shaker and diluted with water. The solution is filtered through a pad of diatomaceous earth and washed successively with hot water. Volatiles are removed under reduced pressure and crude solid obtained is washed with EtOAc (3×50 mL). It is concentrated and dried in vacuum to yield pyrrolo[2,3-c]pyridin-1-yl-acetic acid as a solid (0.565 g).
