실험 절차

A solution of 3-(4-(2-fluoro-4-nitrophenoxy)pyridin-3-yl)prop-2-yn-1-amine (80 mg, 0.26 mmol) in anhydrous CH2Cl2 (2.5 mL) was cooled to 0° C. and treated with chloroacetyl chloride (40 mg, 0.37 mmol) the mixture was stirred at rt for 1 h. The mixture was concentrated under vacuum to removed the solvent and excess reagent and the residue redissolved in CH3CN (1.5 mL), treated with pyrrolidone (55 mg, 0.78 mmol) and stirred at rt for 4 h. The mixture was partitioned between EtOAc and saturated aq. NaHCO3 solution and the organic phase separated, washed with brine, dried (MgSO4) and concentrated to give crude product. The residue was purified by flash chromatography on silica gel eluting with 0-10% MeOH/CH2Cl2 to afford the title compound (40 mg, 39%) as a brown oil. 1H NMR (DMSO-d6) δ 8.66 (s, 1H), 8.50 (d, 1H, J=6.1 Hz), 8.41 (dd, 1H, J=2.8, 10.4 Hz), 8.18-8.15 (m, 2H), 7.51 (dd, 1H, J=8.3, 8.8 Hz), 7.06 (d, 1H, J=5.5 Hz) 4.10 (d, 2H, J=5.5 Hz), 3.01 (s, 2H), 2.47-2.43 (m, 4H), 1.67-1.63 (m, 4H); MS (ESI+): m/z 399.27 (M+H)+.
