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 35):
The method of  claim 34 , wherein\n a mixed liquid of a compound of Formula II, the organic solvent, the condensation agent and the organic base is stirred at 65\u02dc75\u00b0 C. until all solids are dissolved, then the compound of Formula A is added, wherein the compound A is dissolved in the same organic solvent used to dissolve the compound of Formula II; the resultant mixture of the compounds of Formulae II and A is stirred at 70\u02dc80\u00b0 C. for 12\u02dc16 hours 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; and the obtained solid from, filtration is slurried with the organic solvent at 0\u02dc5\u00b0 C. and filtered again.
