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.
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。
