将N-羟基乙酰亚胺酸乙酯(2.00 g,19.4 mmol)、N,N-二异丙基乙胺(3.01 g,23.3 mmol)和4-二甲基氨基吡啶(240 mg,1.96 mmol)溶解于无水二氯甲烷(30 mL)中,并将溶液冷却至0°C。在搅拌下,向冷却的溶液中缓慢加入2,4,6-三甲基苯-1-磺酰氯(4.66 g,21.3 mmol)。反应混合物逐渐升温至室温,并继续搅拌1小时。反应完成后,加入水(40 mL)淬灭反应,随后用二氯甲烷(30 mL,共3次)萃取。合并有机层,用无水硫酸钠干燥,减压浓缩得到粗产物。粗产物通过硅胶快速柱色谱法纯化,使用5%乙酸乙酯的己烷溶液作为洗脱剂,得到O-(2,4,6-三甲基苯磺酰基)乙酰羟肟酸乙酯,为白色固体(5.19 g,产率94%)。产物经1H NMR(400 MHz, CDCl3)、13C NMR(101 MHz, CDCl3)和HRMS(ESI/TOF)表征,数据与预期结构一致。
