Nickel-catalyzed biaryl coupling of heteroarenes and aryl halides/triflates

Org Lett. 2009 Apr 16;11(8):1733-6. doi: 10.1021/ol9001587.

Abstract

Ni-based catalytic systems for the arylation of heteroarenes with aryl halides and triflates have been established. Ni(OAc)(2)/bipy is a general catalyst for aryl bromides/iodides, and Ni(OAc)(2)/dppf is effective for aryl chlorides/triflates. Thiazole, benzothiazole, oxazole, benzoxazole, and benzimidazole are applicable as heteroarene coupling partners. A rapid synthesis of febuxostat, a drug for gout and hyperuricemia, is also demonstrated.
