To a solution of 2-((4-(2-fluoro-4-nitrophenoxy)quinolin-7-yl)oxy)-2-methylpropanoic acid (3 g, 7.75 mmol), EDCI (1.8 g, 9.3 mmol) and HOAT (0.2 g, 1.6 mmol) in CH2Cl2 (60 mL) was added CH3OH (5 mL). The reaction mixture was stirred at room temperature for 1 hour and then diluted with 20 mL of CH2Cl2. The organic phase was separated, washed with water (20 mL) and concentrated in vacuo. The crude product was purified by a column chromatography on silica gel (PE/EtOAc=2:1) to afford the title compound as a yellow oil (3 g, 96.5%).
