実験手順
To a solution of 4-bromo-2-fluorobenzoyl chloride (1 g, 4.21 mmol) in THF (14.04 mL) was added DIEA (1.103 mL, 6.32 mmol) and 2-(benzylamino)ethanol (0.764 g, 5.05 mmol) at room temperature. The reaction mixture was stirred for overnight. The reaction mixture was extracted with EtOAc. The organic layer was washed with water and brine. After dried over anhydrous sodium sulfate, filtered and concentrated in vacuo, the crude N-benzyl-4-bromo-2-fluoro-N-(2-hydroxyethyl)benzamide was used for the next step (83%). LCMS (m/z): 352/354 (MH+), 0.83 min.
