Treatment of alkylarenes with N-bromosuccinimide in a mixture of ethyl acetate and water at 60 °C, a mixture of acetonitrile and water at 80 °C, or a mixture of diethyl carbonate and water under irradiation with a tungsten lamp, followed by a reaction with thioureas or arenethioamides provided the corresponding 2-amino- 4-arylthiazoles or 2,4-diarylthiazoles in good to moderate yields, respectively, in one pot. The present reaction is an efficient one-pot transformation method of alkylarenes into 2-amino-4-arylthiazoles and 2,4-diarylthiazoles directly under mild and transition-metal-free conditions.
