Procedure

In a N,N-dimethylformamide (DMF) solvent, a suspension of 3-bromo-4-hydroxybenzaldehyde (1.0 eq.) and 2-amino-4-(trifluoromethyl)benzenethiol (1.0 eq.) was heated at a temperature of 100° C. After cooling, DMF was removed therefrom under reduced pressure. Methylene chloride was added to the resultant solid, and the produced precipitate was filtered, and washed with methylene chloride to obtain a solid target product.
