Synthesis of certain pyrazolo-1,5-a benzimidazole compounds

摘要

Disclosed is a process that provides steps for synthesizing intermediates useful for appending a N heterocyclic compound to the 3- position of a 4-H-pyrazolo-[1,5-a]benzimidazole compound and further steps that together provide a combined process that yields the target compounds in good yields while using readily available reagents and mild conditions.
