实验步骤: Crude 4-(prop-2-ynyloxy)aniline (0.750 g, 5.10 mmol) and 2,4-dichloro-5-fluoropyrimidine (1.27 g, 0.760 mmol) were stirred in MeOH/water (4:1, 35 mL) at room temperature for 18 h. The reaction mixture was diluted with EtOAc (200 mL) and washed with 1N HCl (50 mL) and brine (50 mL). The organic layer was dried (MgSO4), filtered and concentrated in vacuo. The residue was purified by column chromatography (silica gel, hexanes ramped to EtOAc:hexanes (1:10)) to provide 2-chloro-5-fluoro-N4-[4-(prop-2-ynyloxy)phenyl]-4-pyrimidineamine as a light brown solid (0.514 g). 1H NMR (CDCl3): δ 8.03 (d, J=2.7 Hz, 1H), 7.53 (d, J=8.7 Hz, 2H), 7.02 (d, J=8.7 Hz, 2H), 6.86 (s, 1H), 4.71 (d, J=2.4 Hz, 2H), 2.55 (t, J=2.4 Hz, 1H); LCMS: purity: 99%; MS (m/e): 279 (MH+). washed with 1N HCl (50 mL) and brine (50 mL) The organic layer was dried (MgSO4) filtered concentrated in vacuo The residue was purified by column chromatography (silica gel, hexanes ramped to EtOAc:hexanes (1:10))

实验步骤: 4-(Prop-2-ynyloxy)nitrobenzene (0.910 g, 5.13 mmol), iron (1.42 g, 25.3 mmol), and NH4Cl (0.719 g, 12.8 mmol) were vigorously stirred in EtOH/water (1:1, 55 mL) at 70° C. for 15 minutes. The reaction mixture was filtered hot through Celite and concentrated in vacuo. The residue was suspended in 10% 2N ammoniacal methanol in dichloromethane, sonicated, and filtered through Celite. Concentration gave 4-(prop-2-ynyloxy)aniline as a brown oil which was used without further purification. In general, isolated prop-2-ynyloxyanilines were unstable and were therefore used immediately after the second filtration. 1H NMR (CDCl3): δ 6.82 (d, J=8.7 Hz, 2H), 6.64 (d, J=8.7 Hz, 2H), 4.61 (d, J=2.4 Hz, 2H), 2.50 (t, J=2.4 Hz, 1H).
