以3-硝基-4-碘三氟甲苯为原料合成2-碘-5-三氟甲基苯胺的一般步骤:在23℃条件下,向3-硝基-4-碘三氟甲苯(850mg,2.68mmol)的HOAc-EtOH混合溶液(10mL,体积比1:5)中加入铁粉(750mg,13.43mmol)。将反应混合物于23℃搅拌3小时,随后用饱和NaHCO3溶液(20mL)淬灭反应,并用EtOAc(50mL)稀释。分离有机层和水层,有机层用去离子水(3×10mL)洗涤。合并的有机层经无水Na2SO4干燥后,减压浓缩。残余物通过快速柱色谱法(硅胶为固定相,洗脱剂为己烷:EtOAc,体积比10:1)纯化,得到2-碘-5-三氟甲基苯胺(754mg,收率98%)为黄色固体。1H NMR(400MHz,CDCl3)δ=7.76(dd,J=8.2,0.7Hz,1H),6.96(d,J=1.7Hz,1H),6.72(ddd,J=8.2,2.0,0.6Hz,1H),4.32(brs,2H)。质谱(ESI)m/z:288.0 [M+H]+。
