多肽H2N-Gln-Asp-Leu-Pro-Gly-Asn-Asp-Asn-Ser-Thr-Ala-Thr-Leu-Cys-Leu-Gly-His-His-Ala-Val-Pro-Asn-Gly-Thr-Leu-Val-Lys-Thr-Ile-Thr-Asp-Asp-Gln-Ile-Glu-Val-Thr-Asn-Ala-Thr-Glu-Leu-Val-Gln-Ser-Ser-Ser-Thr-Gly-Lys-Ile-Cys-Asn-Asn-His-Arg-Ile-Leu-Asp-Gly-COOH的合成步骤：

1、合成CTC树脂：称取2.23g CTC Resin（如初始取代度约为0.87mmol/g）和2.33mmol Fmoc-Gly-OH于反应器中，加入适量DCM溶解氨基酸（需要注意，此时CTC树脂体积会增大好几倍，避免DCM溶液过少），再加入5.82mmol DIPEA（Mw：129.1,d：0.740g/ml），反应2-3小时后，可不抽滤溶液，直接加入1ml的HPLC级甲醇，封端半小时。依次用DMF洗涤2次，甲醇洗涤1次，DCM洗涤一次，甲醇洗涤一次，DCM洗涤一次，DMF洗涤2次（这里使用甲醇和DCM交替洗涤，是为了更好地去除其他溶质，有利于后续反应）。得到  Fmoc-Gly-CTC Resin。结构图如下：

2、脱Fmoc：加3倍树脂体积的20%Pip/DMF溶液，鼓氮气30分钟，然后2倍树脂体积的DMF 洗涤5次。得到 H2N-Gly-CTC Resin 。（此步骤脱除Fmoc基团，茚三酮检测为蓝色，Pip为哌啶）。结构图如下：

3、缩合：取5.82mmol Fmoc-Asp(OtBu)-OH 氨基酸，加入到上述树脂里，加适当DMF溶解氨基酸，再依次加入11.64mmol DIPEA，5.53mmol HBTU。反应30分钟后，取小样洗涤，茚三酮检测为无色。用2倍树脂体积的DMF 洗涤3次树脂。（洗涤树脂，去掉残留溶剂，为下一步反应做准备）。得到Fmoc-Asp(OtBu)-Gly-CTC Resin。氨基酸：DIPEA：HBTU：树脂=3：6：2.85：1（摩尔比）。结构图如下：

4、依次循环步骤二、步骤三，依次得到

2）TFA：H2O：TIS=95%：2.5%：2.5%

3）三氟乙酸：茴香硫醚：1，2-乙二硫醇：苯酚：水=87.5%：5%：2.5%：2.5%：2.5%

（前两种适合没有容易氧化的氨基酸，例如Trp、Cys、Met。第三种适合几乎所有的序列。）

6、纯化冻干：使用液相色谱纯化，收集目标峰液体，进行冻干，获得蓬松的粉末状固体多肽。不过这时要取小样复测下纯度 是否目标纯度。

7、最后总结：
