  Method for purifying 5' -protected 2' -deoxypurine nucleosides

  摘要：

  一种用于高效纯化5′保护的2′-去氧嘌呤核苷的方法，先前其高效生产曾经困难。通过获得含有类似腈结构的溶剂的包含晶体，可将杂质分离以纯化5′保护的2′-去氧嘌呤核苷。该发明使得在大规模上轻松合成高纯度的保护去氧嘌呤核苷成为可能，而此前通常通过柱层析法进行。

  A method for efficiently purifying 5′ protected 2′-deoxypurine nucleosides, efficient production of which has previously been difficult. Impurities can be separated by obtaining the 5′ protected 2′-deoxypurine nucleoside as an inclusion crystal including a solvent such as that having a nitrile structure in order to purify the 5′ protected 2′-deoxypurine nucleoside at a high purity. This invention enables synthesis of highly purified protected deoxypurine nucleosides easily on a large scale, which has previously been performed by column chromatography method.
