実験手順: A solution of 4-methoxy-3-(2-methoxyethoxy)aniline (5 g, 25.3 mmol) and diethyl ethoxymethylenemalonate (6 ml, 30 mmol) was heated at 110° C. for 30 minutes. Phenyl ether (5 ml) was added and the mixture was heated at 240° C. for 6 hours. The mixture was allowed to cool and diluted with petroleum ether. The resulting solid was collected by filtration and purified by reverse phase chromatography on a Diaion (trade mark of Mitsubishi) HP20SS resin column eluting with acetonitrile/water (40/60) to give 6-methoxy-7-(2-methoxyethoxy)-1,4-dihydroquinolin-4-one (500 mg, 8%). to cool The resulting solid was collected by filtration purified by reverse phase chromatography on a Diaion (trade mark of Mitsubishi) HP20SS resin column eluting with acetonitrile/water (40/60)

実験手順: A mixture of 4-methoxy-3-(2-methoxyethoxy)nitrobenzene (7 g, 30 mmol) and 10% palladium-on-charcoal catalyst (1.4 g) in ethyl acetate (70 ml) was stirred under hydrogen at 3.3 atmospheres pressure for 1 hour. The catalyst was removed by filtration through diatomaceous earth and the solvent removed by evaporation. The solid residue was suspended in ethyl acetate, collected by filtration and dried under vacuum to give 4-methoxy-3-(2-methoxyethoxy)aniline (6.1 g, 100%). The catalyst was removed by filtration through diatomaceous earth the solvent removed by evaporation collected by filtration dried under vacuum

実験手順: 2,4-Dichloro-1,3,5-triazine (89.1 mg, 0.5944 mmol) was dissolved in DMF (0.5 ml) and cooled to 0° C. To this solution were added DIEA (104 μl), 4-methoxy-3-(2-methoxy-ethoxy)phenylamine (TFA salt)(264 mg, ˜0.59 mmol) and DIEA (208 μl) in DMF (1 ml). The reaction mixture was kept at 0° C. for 15 to 30 min and then at RT for 15 min to 2 h. The reaction mixture was diluted with EtOAc and washed with brine. The organic layer was dried over Na2SO4, filtered, and evaporated in vacuo, to give (4-chloro-[1,3,5]triazin-2-yl)-[4-methoxy-3-(2-methoxy-ethoxy)-phenyl]amine. at RT for 15 min to 2 h washed with brine The organic layer was dried over Na2SO4 filtered evaporated in vacuo
