Method for purifying 5′ -protected thymidines and novel derivatives thereof |
abstract |
This invention provides a method for efficiently purifying 5′-protected thymidines which cannot be efficiently purified by the prior art. Impurities can be separated by obtaining crystals including a carbonyl-containing solvent to provide a highly pure 5′-protected thymidine. Thus, this invention allows 5′-protected thymidines, which cannot be purified in an industrial scale by the prior art, to be easily provided with a high purity in a large scale. |
