実験手順: To a solution of (5-fluoro-pyridin-2-yl)-hydrazine (1.62 g, 12.8 mmol), 2-(morpholin-4-yl)propanoic acid (Enamine, 2.50 g, 12.8 mmol), HOBt.H2O (196 mg, 1.28 mmol) and Et3N (2.14 mL, 15.3 mmol) in DCM (50 mL) was added EDC (2.94 g, 15.3 mmol) and the brown solution stirred at RT for 16 h. Water (20 mL) and brine (20 mL) were added, and the mixture shaken. The aqueous layer was extracted with DCM (20 mL), then the combined organics were passed through a hydrophobic frit and concentrated in vacuo to give the title compound as a brown foam (3.43 g, >99%). LCMS (Method 3): Rt 0.44 min, m/z 269 [MH+]. the mixture shaken The aqueous layer was extracted with DCM (20 mL) concentrated in vacuo
