Ethyl 4-(2-oxo-3-(2-(piperidin-1-yl)ethyl)-2,3-dihydro-1H-imidazo[4,5-b]pyrazin-5-yl)benzimidate hydrochloride. 4-(2-Oxo-3-(2-(piperidin-1-yl)ethyl)-2,3-dihydro-1H-imidazo[4,5-b]pyrazin-5-yl)benzonitrile (0.5 g., 1.43 mmol) was placed in anhydrous ethanol (5 mL) and cooled on an ice bath. The mixture was charged with hydrogen chloride gas for 15 min, capped and allowed to stir overnight while warming to rt. The solvent was removed and the residue treated with ether, filtered and dried under high vacuum to yield the title compound (0.4 g., 64.6% yield). MS (ESI) m/z 395.6[M+1]+
