Reaction Steps

10% Pd/C (40 mg) was added to a stirred solution of Ethyl imidazo[1,2-a]pyrazine-2-carboxylate (410 mg, 2.15 mmol) and conc.HCl (0.5 mL) in EtOH (9.5 mL) under inert atmosphere. The reaction mixture was stirred continuously under hydrogen atmosphere for 16 h. The reaction mixture was filtered over a celite bed- and the filtrate was concentrated under reduced pressure to afford a solid product, which was washed with diethyl ether and dried to afford 400 mg of the title compound as a yellow solid.
