Abstract
AbstractA mild and convenient method for the arylation of benzoxazoles with benzoyl chlorides is reported. This facile protocol used only N,N‐diisopropylethylamine (DIPEA) as an additive. Under the optimal reaction conditions, a wide range of benzoxazoles and benzoyl chlorides were tolerated. With this strategy, benzothiazoles and benzoyl chlorides also reacted well to afford the desired product 2‐aryl benzothiazoles in moderate yields.
