To a solution of 1.7 g (0.01 mole) of 4-trifluoromethyl-2-aminothiazole in 50 ml of dry ethylacetate was added all at once to a solution of 2.16 g (0.01 mole) of freshly prepared 2,6-dichlorobenzoylisocyanate dissolved in 10 ml of dry ethylacetate. The mixture was allowed to stir at 25° for 4 hours. The solvent was evaporated in vacuo, ether was added to the residue, and the solid was removed by filtration to give 3.7 g of product, m.p. 210°-213°. The infrared and nuclear magnetic resonance spectra were consistent with the proposed structure.
