PROCEDURE
实验过程
A solution of (S)-(3-fluoro-4-(trifluoromethoxy)phenyl)(3-fluoropyridin-2-yl)methanamine hydrochloride (400 mg, 1.174 mmol, Intermediate 6), 1-(2-(tert-butoxy)-2-oxoethyl)-6-oxo-1,6-dihydropyridine-3-carboxylic acid (327 mg, 1.292 mmol) and HATU (491 mg, 1.292 mmol) in DMF (10 mL) was treated with TEA (0.490 mL, 3.52 mmol). The reaction was then stirred at 23° C. under nitrogen. After 17 h, the solution was diluted with EtOAc (100 mL) and washed with brine (100 mL), dried over MgSO4, concentrated in vacuo and purified by silica gel chromatography (eluent: 5-30% EtOAc/DCM), affording the title compound as a colorless oil. The compound was taken forward to the next step. MS (ESI, positive ion) m/z: 540.2 (M+H).
