Abstract:
This disclosure provides a process for preparing 1-(arylmethyl)quinazoline-2,4(1H,3H)-diones, specially provides a method for preparing the compound of Formula I, and the method comprises the step of reacting the compound of Formula II with the compound of Formula A in the presence of a condensation agent, an organic base and an organic solvent by condensation.

Claim (Index 20):
The method of  claim 17 , wherein\n a mixed liquid of a compound of Formula II, an organic solvent, a condensation agent and an organic base is stirred at 65\u02dc75\u00b0 C. until all solids are dissolved, then the compound of Formula A is added; a mixture of the compounds of Formulae II and A is stirred at 70\u02dc80\u00b0 C. to allow for the condensation reaction; after the completion of stirring at 70\u02dc80\u00b0 C., the reaction liquid is cooled to 0\u02dc5\u00b0 C. and stirred for another 4\u02dc6 hours, and filtered to provide the compound of Formula. I.
