실험 절차
A solution of 5,6-dichloro-nicotinoyl chloride from step (a) above (1.73 g, 8.22 mmol)) in CH2Cl2 (50 mL) was added to a mixture of 28% aq. NH4OH (20 mL), water (20 mL) and CH2Cl2 (50 mL), and vigorously stirred at room temperature for 2 h. The organic phase was separated, washed with brine (50 mL), dried over Na2SO4, filtered and concentrated in vacuo to give the title compound as a white solid. MS (ESI, pos. ion) m/z: 191 (M+1).
