A round bottomed flask charged with [4-(2,4-dioxo-1,4-dihydro-2H-quinazolin-3-yl)-phenyl]-acetic acid ethyl ester (Intermediate H) (2.0 g, 6.17 mmol), K2CO3 (2.5 eq, 2.14 g, 15.52 mmol), and 2-bromo-N-(5-chloro-2,4-dimethoxy-phenyl)-acetamide (Intermediate C) (1.02 eq, 1.99 g, 6.49 mmol) is treated with dry DMF (20 ml). The reaction is stirred at RT for 72 hours. The reaction mixture is diluted with distilled water and stirred for 15 minutes. The precipitate formed was filtered, washed with water and dried under vacuum to give the title compound; [M+H]+ 552
