4-[(3R,4R)-(4-Hydroxytetrahydrofuran-3-yl)oxy]-2-(1-piperazinyl)quinazoline 1/2 hydrochloride (cf. Example 21) (178 mg) is dissolved in methanol (3 ml) with heating, and thereto is added 2N HCl-methanol (0.32 ml) and acetone (10 ml), and the mixture is allowed to stand at room temperature. The precipitated crystals are separated by filtration to give 4-[(3R,4R)-(4-hydroxytetrahydrofuran-3-yl)oxy]-2-(1-piperazinyl)quinazoline monohydrochloride (124 mg) as crystals.
