Procedure

To a solution of (R)-1-((4-(4-aminophenoxy)quinolin-7-yl)oxy)propan-2-ol (2.5 g, 11.9 mmol), 1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carb oxylic acid (2.0 g, 8.6 mmol) and HOAT (0.2 g, 1.6 mmol) in DCM (35 mL) was added EDCI (1.9 g, 9.7 mmol). The reaction mixture was stirred at 43° C. for 12 hours, then cooled to room temperature and diluted with a mixture of DCM and H2O (50 mL/50 mL). The organic phase was separated, dried over Na2SO4 and concentrated in vacuo. The residue was purified by a column chromatography on silica gel (EtOAc) to afford the title compound as a yellow solid (0.6 g, 14.3%).
