実験手順
A mixture of 6.02 g of the product of Step C, 200 ml of xylene, 2 g of 2-amino-thiazole and 20 g of siliporite NK20 was refluxed for 2 hours and the resulting product was crystallized from acetic acid to obtain 5.54 g of N-(2-thiazolyl)-2,4-dihydroxy-8-trifluoromethyl-quinoline-3-carboxamide in the form of colorless crystals melting at 260° C.
