4-(Benzyloxy)-2-methylaniline → 1-(2-Methyl-4-benzyloxyphenyl)-4-[(2-hydroxyethyl)amino]-6-beta,beta,beta-trifluoroethoxy-2,3-dihydropyrrolo[3,2-c]quinoline

Reaction Steps

4-Oxo-6-β,β,β-trifluoroethoxy-2,3,4,5-tetrahydrofuro[3,2-c]quinoline(5.7 g, 20.0 mmol) was dissolved in diethylene glycol(70 ml) and crude 4-benzyloxy-2-methyl aniline(5.6 g, 26.0 mmol) was added. The reaction mixture was refluxed at 250° C. for 15 hours. The reaction mixture was dissolved in water, extracted with dichloromethane, and the organic layer was washed with water for 3 times. The organic layer was dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography(ethyl acetate:dichloromethane=1:1) to obtain 4.5 g of desired compound as solid in 47% of yield.
