将5-甲基-2-硝基苯甲酸(8g,44.198mmol)溶于甲醇(80mL)中,并将溶液冷却至0℃。在搅拌下,缓慢滴加硫酸(5mL)。随后,将反应混合物加热至90℃,并在该温度下持续搅拌16小时。反应进程通过薄层色谱(TLC,展开剂为50%乙酸乙酯/己烷)进行监测。反应完成后,减压蒸馏除去过量的甲醇。将残余物倒入水(150mL)中,并用乙酸乙酯(150mL×2)进行萃取。合并有机相,依次用饱和碳酸氢钠溶液(50mL×2)和盐水(20mL)洗涤。有机层经无水硫酸钠干燥后,过滤并浓缩,得到5-甲基-2-硝基苯甲酸甲酯(产率:8g,93%)。产物结构经1H NMR(400MHz,CDCl3)确认:δ7.86-7.84(d,1H,J = 8Hz),7.48(s,1H),7.40-7.38(d,1H,J = 8Hz),3.91(s,3H),3.47(s,3H)。
