Reaction Steps
To a solution of 2-(methoxycarbonyl)-3-[4-[2-(6-quinolinoxy)ethoxy]phenyl]propionic acid (2.11 g, 5.29 mmol) in benzene (20 ml) at room temperature is added thionyl chloride (0.76 g, 6.34 mmol). Then the mixture was heated at 80° C. for 90 min. After cooled to room temperature, the solvent is removed under a vacuum. To the residue is added 28% ammonia solution (5.49 ml, 79.30 mmol) at room temperature. The mixture is stirred for 30 min, dissolved in ethyl acetate (20 ml), washed with brine (3×15 ml), dried over sodium sulfate, and concentrated. The crude product is crystallized from ethanol to give title compound (1.20 g, 57%). HRMS calcd for C22H26N2O5: 398.4558. Found: 398.4554. MA calcd for C22H26N2O5: C, 66.32%; H, 6.58%; N, 7.03%. Found: C, 66.44%; H, 6.54%; N, 7.05%
