METHODS FOR PREPARING 7-(2'-SUBSTITUTED-ß-D-RIBOFURANOSYL)-4-(NR2R3)-5-(SUBSTITUTED ETHYN-1-YL)-PYRROLO[2,3-D]PYRIMIDINE DERIVATIVES

摘要

Disclosed are methods and intermediates for the preparation of 7-(2'-R1-substituted-ß-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.
