Similarly, 2-bromo-4-t-butylaminocarbonylthiazole is prepared by following the same procedure but using 2-bromo-4-carboxythiazole in place of the 5-position isomer. Similarly, by replacing t-butylamine with the amine reagents set forth in Preparation 2, the corresponding 2-bromo-4- and 5-substituted aminocarbonylthiazoles are respectively prepared.
