Reaction Steps

In a DMF (3 mL) solvent, a solution including 2-amino-4-trifluoromethylbenzenethiol (100 mg, 0.44 mmol) and 3-bromo-4-hydroxybenzaldehyde (88.4 mg, 0.44 mmol) was heated at a temperature of 100° C. for 2.5 hours. After DMF was evaporated, the residual was distributed between methylene chloride and water, and an organic layer was evaporated. The produced solid was filtered, and washed with ethyl acetate to obtain a solid Compound 119.
