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 28):
The method of  claim 26 , wherein 2) comprises one or more of the following features:\n the organic solvent is N-methyl-2-pyrrolidone and/or N,N-dimethylformamide; the reflux conditions comprise stirring at 105\u02dc115\u00b0 C. for 12\u02dc18 horns; for 1 mol of the compound of Formula IV-TMS, 1.0\u02dc1.3 mol of the compound of Formula V is used; and after the refluxing is finished, dioxane is added to the reaction liquid, which is cooled to 65\u02dc75\u00b0 C., then alcoholic solvent is added, and the mixture is stirred at 65\u02dc75\u00b0 C. for about 0.5\u02dc1 hour; the reaction liquid is cooled to 0\u02dc5\u00b0 C., stirred for 1\u02dc2 hours, and filtered to provide the compound of Formula III.
