Procedure
A mixture of dimethyl[(6-methanesulfonamido-4-quinazolinylamino)methylene]propanedioate (7.2 g) and diphenyl ether (43 ml) was stirred at 250° C. for 15 minutes and then cooled to ambient temperature to give crystals, which were filtered off and washed with a mixture of chloroform and methanol to give crystalline methyl 4-oxo-10-methanesulfonamido-4H-pyrimido[1,2-c]quinazoline-3-carboxylate (4.72 g).
