Versuchsvorschrift

4-[(2R,3R)-(2,3,4-Trihydroxybutan-1-yl)oxy]-2-(1-piperazinyl)quinazoline (cf Example 64) (0.5 g) is dissolved in methanol (40 ml), and thereto is added 2N HCl-methanol (0.82 ml), and the mixture is evaporated to dryness under reduced pressure. The resulting residue is recrystallized from ethanol to give 4-[(2R,3R)-(2,3,4-trihydroxybutan-1-yl)oxy]-2-(1-piperazinyl)quinazoline monohydrochloride (0.14 g).
