    摘要: Disclosed are methods and intermediates for the preparation of 7-(2′-R1-substituted-β-D-ribofuranosyl)-4-amino-5-(optionally substituted ethyn-1-yl)-pyrrolo[2,3-d]pyrimidine compounds. These compounds are useful in treating viral infections caused by a flaviviridae family virus, such as hepatitis C virus. Such 7-(2′-substituted-β-D-ribofuranosyl)-4-amino-5-(optionally substituted ethyn-1-yl)-pyrrolo[2,3-d]pyrimidine compounds are represented by Formula I as follows: wherein, each of R1, R2, and R3 are as defined herein.
