Reaction Steps

4-Chloro-8-methoxy-quinoline-3-carboxylic acid ethyl ester (300 mg, 1.13 mmol) was treated with furfurylamine following general procedure B to afford 8-methoxy-4-[(tetrahydro-furan-2-ylmethyl)-amino]-quinoline-3-carboxylic acid ethyl ester (280 mg). Thus obtained amino-ester was hydrolyzed to the corresponding acid in quantitative yield using general procedure D and then transformed into the corresponding ethylamide (220 mg) following general procedure E. The above ethylamide (0.67 mmol) was subjected to reaction with methyl chloroformate according to general procedure F to furnish 3-ethyl-7-methoxy-1-(tetrahydro-furan-2-ylmethyl)-1H-pyrimido[5,4-c]quinoline-2,4-dione (30 mg). LCMS: m/z 356 [M+1]+.
