Versuchsvorschrift
7-(3-Morpholinopropoxy)-3-((pivaloyloxy)methyl)-3,4-dihydroquinazolin4-one (680 mg, 1.6 mmol) was stirred in methanolic ammonia (20 ml) at 40° C. for 6 hours then for 18 hours at ambient temperature. The solvent was removed by evaporation, the residue was triturated with ether/isohexane and collected by filtration to give 7-(3-morpholinopropoxy)-3,4-dihydroquinazolin-4-one (450 mg, 92%) as a white solid.
