A series of tetrasubstituted 7-azabenzofurans displays remarkable pan-genotype inhibition of HCV NS5B polymerase. One of them has been identified as a potential clinical candidate. Completely different from the original synthesis of a common and key intermediate for this class of compounds, two novel and improved synthetic approaches are developed. Almost every step of the synthesis has been optimized, including several important but not fully explored transformations, such as radical bromination with methyl pyridine and cyanide substitution with TMSCN. The 7-azabenzofuran core is prepared by an acylation-heterocyclization reaction, using acyl chloride as both the reactant and the activation reagent for the N-oxide substrate. Compared with the BMS synthesis, the overall yield has been tripled, and those harmful or cost-effective synthetic steps have been reduced. Furthermore, a transition-metal-free synthetic method for the construction of 3-cyano substituted 7-azabenzofurans is presented.
