To a solution of 3-amino-4-(2-hydroxyethylamino)benzonitrile (1.21 g) and 4-(1-tert-butoxycarbonylpyrrolidin-3-yloxy)phenoxyacetic acid (2.30 g) in chloroform (50 ml) was added 1-ethoxycarbonyl-2-ethoxy-1,2-dihydroxyquinoline (2.19 g), and the mixture was stirred at room temperature for 15 hours. After completion of the reaction, the solvent was evaporated and the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:4) to give the title compound (2.56 g).
