Procedure
To a solution of (Z-2-(8,9-dimethoxy-2,3-dihydroimidazo[1,2-c]quinazolin-5-yl)-1-(3-pyridinyl)ethenol (16.8 mg, 0.05 mmol)) in dioxane (15 ml) at room temperature was added aqueous 6N HCl solution (0.05 ml). After being stirred for 30 minutes, the mixture was dried under reduced pressure to give (Z)-2-(8,9-dimethoxy-2,3-di-hydroimidazo[1,2-c]quinazolin-5-yl)-1-(3-pyridinyl)ethenol hydrochloride (18.5 mg, quantitative) as a yellow solid.
