Multi-step continuous flow synthesis of fluconazole

Abstract

The development of a flow chemistry approach to the anti-fungal fluconazole is described. A continuous, two-reactor, three-step synthesis of fluconazole from 2-chloro-2′,4′-difluoroacetophenone was achieved with no intermediate purification. The synthesis has been successfully demonstrated on a Vapourtec commercial flow chemistry system. [Figure not available: see fulltext.].
