Direct Amination of Azoles via Catalytic C-H, N-H Coupling

C-H, N-H Coupling of azoles takes place with several amines in the presence of a copper catalyst to undergo amination at the 2-position. The reaction of benzothiazole with N-methylaniline in the presence of sodium acetate and 20 mol % Cu(OAc)(2) in xylene under an oxygen atmosphere afforded the aminated product in 81% yield.
