carboxylic acids with amines was developed for the synthesis of a broad scope of amides in a simple, mild, highly efficient, robust and practical manner (>110 examples, >90% yields in most cases). The direct click reactions of acids and amines on a gram scale are also demonstrated using an extremely easy work-up and purification process of washing with 1 M aqueous HCl to provide the desired amides in

discovery of coupling reagents which gave an unprecedented impeteus to the development of peptide synthesis. Of course, in these methods high reactivity of carboxyl function towards nucleophilic attack is achieved, but rigorous conditions such as use of base, temperature etc. are required. Moreover, the electron withdrawing groups like halogen which enhances the electrophilicity of carboxyl carbon, increases

The present invention relates to compounds of Formula I, or a pharmaceutically acceptable salt, ester, or prodrug, thereof:
which inhibit serine protease activity, particularly the activity of hepatitis C virus (HCV) NS3-NS4A protease. Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.
