Procedure

120 mg of (6-methylimidazo[1,2-a]pyridin-2-yl)phenylmethanone are taken up in 2 mL of ethanol and the solution is treated with 1.5 mL of a 4N solution of hydrogen chloride in dioxane and then with 2 mL of diethyl ether. The crystals obtained are filtered off and washed with diethyl ether, and then dried. 77 mg of (6-methylimidazo[1,2-a]pyridin-2-yl)phenylmethanone hydrochloride (1:1) are obtained in the form of a beige-colored solid.
