Procedure

4-[trans-(4-Hydroxytetrahydrofuran-3-yl)oxy]-2-(1-piperazinyl)quinazoline (cf. Example 11) (200 mg) is dissolved in acetone (20 ml) with heating, and the solution is filtered, and the filtrate is concentrated and thereto is added acetic acid (50 mg), and the mixture is allowed to stand at room temperature. The precipitated crystals are separated by filtration to give 4-[trans-(4-hydroxytetrahydrofuran-3-yl)oxy]-2-(1-piperazinyl)quinazoline monoacetate (171 mg).
