在装有搅拌器和滴液漏斗的250 mL三口烧瓶中,加入16.2 g氢氧化钠和40 mL蒸馏水,匀速搅拌至完全溶解,并用冷水冷却到5 ℃。在不断搅拌下缓慢加入15.7 g溴,加完后继续搅拌20 min,确保溴完全反应,从而制备NaOH-NaOBr混合溶液。保持低温环境和均匀搅拌条件下,逐步滴加先前合成的4-氨基苯甲酰胺溶解于50 mL蒸馏水中的溶液。滴加完毕后进行重排反应,控制反应温度为30 ℃,维持此条件30 min。随后开始缓慢升温,确保反应温度保持在85 ℃左右,继续反应35 min。冷却并抽滤得到的产物,用乙醚萃取,经真空干燥处理,最终获得10.4 g对苯二胺,收率为97.6%,纯度为99.6%。
接着,将对苯二胺溶解于二氯甲烷中,并加入三乙胺。随后,滴加二碳酸二叔丁酯的二氯甲烷溶液,反应15小时后减压蒸除溶剂。浓缩后的产物经硅胶柱层析(洗脱剂为乙酸乙酯和石油醚体积比1:10)纯化得到目标化合物特定基氨基甲酸脂酶。
