実験手順: 4-Chloro-8-methoxy-quinoline-3-carboxylic acid ethyl ester (250 mg, 0.94 mmol) was treated with 4,4-difluoro-cyclohexylamine following general procedure B to afford 4-(4,4-difluoro-cyclohexylamino)-8-methoxy-quinoline-3-carboxylic acid ethyl ester (192 mg). Thus obtained amino-ester (92 mg, 0.25 mmol) was subjected to reaction with 1-chloro-3-isocyanato-benzene according to general procedure C to furnish 3-(3-chloro-phenyl)-1-(4,4-difluoro-cyclohexyl)-7-methoxy-1H-pyrimido[5,4-c]quinoline-2,4-dione (69 mg). LCMS: m/z 472 [M+1]+. 1H NMR (400 MHz, CDCl3): δ 9.56 (s, 1H), 7.58 (m, 1H), 7.48 (m, 1H), 7.38 (m, 1H), 7.24 (m, 1H), 7.06-7.14 (m, 2H), 6.48 (m, 1H), 5.09 (m, 1H), 4.08 (s, 3H), 2.84 (m, 2H), 2.23 (m, 2H), 1.80-2.00 (m, 4H) ppm.

実験手順: As described for example 2b, 5-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-pyrazine-2-carboxylic acid (100 mg, 0.32 mmol) was converted, using 4,4-difluorocyclohexylamine instead of aminomethylcyclopropane to the title compound (SiO2, heptane:ethyl acetate=90:10 to 60:40, 37 mg, 27%) which was obtained as a white solid. MS: m/e=429.2 [M+H]+.
