Procedure

To a solution of 4-{5-[2-amino-5-(3-methoxy-phenyl)-pyridin-3-yl]-[1,3,4]oxadiazol-2-yl}-piperidine-1-carboxylic acid tert-butyl ester (200 mg, 0.44 mmol) in chloroform (10 mL) was added 2M HCl in diethyl ether (10 mL) at 0° C., and the reaction mixture was stirred for 4 h at 0° C. After completion of the reaction, solvents in reaction mixture were evaporated under vacuum to get crude product. Crude product was purified by washing with ethyl acetate and hexane to afford the title compound as a pale yellow powder.
