Procedure

To a solution of tert-butyl 1,3-dimethyl-6,7-dihydro-1H-pyrazolo[4,3-c]pyridine-5(4H)-carboxylate (3.00 g) in MeOH was added a solution of HCl in EtOAc (3.0 M). White solid was precipitated out after 3.0 h reaction. The resulted mixture was filtered and the residue was dried to give the title compound as a white solid (2.00 g, 90.90%). The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 152.21 (M+1).
