合成路线 1(1. 合成:100286-90-6)
产率:90%
合成条件:Stage #1: With triethylamine In pyridine; dichloromethane at 30 - 40℃; for 1.50 h; Stage #2: for 0.50 h;
实验步骤:将7-乙基-10-羟基喜树碱(4.5g)和吡啶(60ml)加入反应容器中。 在30-40℃下加入[1,4'] - 联哌啶基-r-碳酰氯盐酸盐(3.44g)和三乙胺(4.8ml)在75ml二氯甲烷中的溶液。 将混合物在30-40℃下搅拌1.5小时。 加入4-哌啶子基哌啶(0.58g)并将混合物搅拌0.5小时。 蒸馏出二氯甲烷和吡啶,直至残余物的体积为约25ml。 加入乙腈(100ml),将混合物加热至约60℃。 将混合物冷却至室温,加入15ml 5%盐酸水溶液。 将混合物在室温下搅拌约20小时。 将混合物冷却至0 +/- 5.过滤结晶化合物并用乙腈:水10:1混合物(10ml)和乙腈(10ml)洗涤。 减压干燥产物。 产量为6.4克(90%)。

合成路线 2(2. 合成:100286-90-6)
产率:100%
合成条件:With hydrogenchloride In dichloromethane; water at 0℃; for 2 - 3 h;
实验步骤:将实施例1的产物溶解在DCM中并冷却至0℃。向该溶液中逐滴加入12N HCl并搅拌2-3小时。 蒸发溶剂,得到固体,将其溶解在甲醇中,加入乙醚使其沉淀。 用乙醚洗涤沉淀3次,得到纯产物,即伊立替康的盐形式(即式III-A化合物)。 所需产物的产率是定量的。 或者,将实施例1的产物溶于水中,并将12N HCl逐滴加入溶液中。 产物沉淀出来并通过过滤获得。 产量为95%。
