Significance

Over 50 examples of a new nickel-catalyzed C-H arylation of thiazoles, benzothiazoles, oxazoles, benzoxazoles, and benzimidazoles with haloarenes is described. The practical potential of the reaction was illustrated by the syntheses of febuxostat (Adenuric®, a xanthine oxidase inhibitor), tafamidis (effective for the treatment of TTR amyloid neuropathy) and texaline (a natural product with antitubercular activity).
