Procedure

To 8-methyl-5-methylsulfanyl-1,3-diphenyl-1H,8H-pyrimido[4,5-d]pyrimidine-2,4,7-trione 26 (149 mg) obtained in Step 6 was added toluene (2 ml), 4-chloroaniline 27 (97 mg) was added, and the mixture was stirred under reflux for 3.5 hrs. After allowing to cool to room temperature, diethyl ether was added. The crystals were collected by filtration, washed with diethyl ether and dried to give 5-(4-chloro-phenylamino)-8-methyl-1,3-diphenyl-1H,8H-pyrimido[4,5-d]pyrimidine-2,4,7-trione 28 (94 mg, yield 53%) as colorless crystals.
