We report here an efficientmethod for the synthesis and characterization of [H-NMP]HSO4 and its application as an efficient catalyst and solvent for preparation of azides from corresponding alcohols under mild conditions. This processor showed high chemoselectivity for conversion of various alcohols to their corresponding azides.
Compounds effective in inhibiting replication of Hepatitis C virus (“HCV”) or other viruses are disclosed. This invention is also directed to compositions comprising such compounds, co-formulation or co-administration of such compounds with other anti-viral or therapeutic agents, processes and intermediates for the syntheses of such compounds, and methods of using such compounds for the treatment of HCV or other viral infections.
