Procedure

4-Chloro-8-methoxy-quinoline-3-carboxylic acid ethyl ester (267 mg, 1.0 mmol) was treated with isopropylamine (1.5 mmol) following general procedure B to afford 4-isopropylamino-8-methoxy-quinoline-3-carboxylic acid ethyl ester (256 mg). 3-Ethyl-1-isopropyl-7-methoxy-1H-pyrimido[5,4-c]quinoline-2,4-dione (14 mg) was prepared from 4-isopropylamino-8-methoxy-quinoline-3-carboxylic acid ethyl ester (0.10 mmol) and ethyl isocyanate (0.4 mmol) following general procedure C. LCMS: m/z 314 [M+1]+.
