Efficient protocols for microwave-assisted catalyzed amination of halogeno-phenothiazines are described. Phenothiazineanalogues of Troger'sbase (PTB) were obtained by condensation of amino-phenothiazines with formaldehyde in HCl/EtOH/H2O and structurally characterized by NMR and XRD analyses. The formation of PTB isomers was predicted by computational analysis based on theoretical methods (DFT and
