Reaction Steps

A solution of (2-cyclopropylcarbamoyl-phenyl)-carbamic acid methyl ester was dissolved in MeOH (100 ml) and treated with NaOMe (0.5 M, 5 ml, 2.5 mmol) and the mixture heated to reflux for 12 h. The mixture was cooled and filtered to give 4.05 g (53%) of 3-cyclopropyl-1H-quinazoline-2,4-dione as a white solid.
