We report the synthesis of several new 3-aminohydantoinyl-1.2-benzothiazine derivatives and propose an another mechanism of the cyclization to the hydantoins for the development candidates of COX-2 inhibitors. 3-Aminohydantoins 3a-d were prepared through cyclization of the condensation products that were formed by heating amino acids and tert-bytyl carbazate in quinoline according to the method of Lalezari.
