Abstract
The invention is directed to processes for synthesizing bicyclic nucleoside antiviral compounds and for synthesizing the intermediates used in the process. The invention is also directed to novel intermediate compounds useful in the process. The antiviral compounds are useful in the treatment of herpes zoster (i.e., varicella zoster virus, VZV, shingles) and for the prevention of post herpetic neuralgia (PHN) resulting from this viral infection.
