Procedure

4-Chloro-8-methoxy-quinoline-3-carboxylic acid ethyl ester (250 mg, 0.94 mmol) was treated with 4-methoxybenzylamine following general procedure B to afford 8-methoxy-4-(4-methoxy-benzylamino)-quinoline-3-carboxylic acid ethyl ester (290 mg). Thus obtained amino-ester was hydrolyzed to the corresponding acid using general procedure D and then transformed into the corresponding ethylamide (190 mg) following general procedure E. The above ethylamide (0.41 mmol) was subjected to reaction with methyl chloroformate according to general procedure F to furnish 3-ethyl-7-methoxy-1-(4-methoxy-benzyl)-1H-pyrimido[5,4-c]quinoline-2,4-dione (110 mg). LCMS: m/z 422 [M+1]+.
