반응 단계
A solution of 5-fluoro-2-hydrazinyl-pyridine (0.59 g, 4.65 mmol), isobutyric acid (528 mg, 6 mmol), and HOBt hydrate (153 mg, 1 mmol) in DCM (10 mL) was treated with EDCl HCl (1.15 g, 6 mmol). The reaction mixture was stirred at RT for 40 min, poured onto sat. aq. sodium bicarbonate (40 mL), extracted with four portions of DCM, dried (Na2SO4), evaporated and purified by FCC (DCM/EtOAc 9/1 to 3/7) to give the title compound (0.42 g, 46%). LCMS (Method 8): Rt 2.46 min, m/z 198 [MH+].
