Reaction Steps

In an acetic acid (0.42 mL) solvent, a mixture including 2-amino-4-(trifluoromethyl)benzenethiol (100 mg, 0.44 mmol), 3,5-dihydroxybenzaldehyde (60 mg, 0.44 mmol), and sodium acetate (107 mg, 1.30 mmol) was refluxed for 6.5 hours. After cooling, the reaction mixture was distributed between ethyl acetate and water, and an organic layer was dried by using MgSO4, filtered, and evaporated under reduced pressure. The residual was purified by silica gel column chromatography using hexane and ethyl acetate (2:1) as a developer to obtain a solid Compound 36 (50.6 mg, 37%).
