In the present study, the possibility of converting [5-(1,1,2,2-tetrafluoroethoxy)-4-phenylthiazol-2-yl]amine to 2-halothiazoles and an azo compound via diazotation of the amine functionality was demonstrated. It was found that the reaction of [5-(1,1,2,2-tetrafluoroethoxy)-4-phenylthiazol-2-yl]amine with acyl and sulfonyl chlorides leads to products resulting from substitution exclusively at the exocyclic nitrogen atom. The halogen atom at position 2 of thiazole ring is substituted by S-nucleophiles or hydrogen atom upon catalytic hydrogenation on Pd/C. 2-Bromo-5-(1,1,2,2-tetrafluoroethoxy)-4-phenylthiazole was successfully employed in the synthesis of the corresponding α-thiazolylbenzyl alcohol and 2-formylthiazole via conversion to a organomagnesium intermediate. The stability of the tetrafluoroethoxy group in the above transformations was demonstrated.
