Procedure

In a dimethyl sulfoxide (DMSO) (2 mL) solvent, a solution including 3-bromo-4-hydroxybenzaldehyde (163.7 mg, 0.81 mmol) and 2-amino-4-chlorobenzenethiol (100 mg, 0.45 mmol) was refluxed for 1 hour. After cooling, the residual was distributed between ethyl acetate and water, and an organic layer was dried by using MgSO4, filtered, and evaporated under reduced pressure. The resultant residual was added to water, and then, the precipitate was filtered and the filtered product was washed with water and methylene chloride to obtain a solid Compound 95 (46.4 mg, 17.6%).
