実験手順: In a DMF (3 mL) solvent in the presence of Na2S2O5 (120.3 mg, 0.63 mmol), a solution including 2-amino-4-chlorobenzenethiol (100 mg, 0.63 mmol) and syringaldehyde (115.3 mg, 0.63 mmol) was heated at a temperature of 80° C. for 22 hours. After DMF was evaporated, water was added thereto. The produced precipitate was filtered, and washed with water to obtain Compound 126. After DMF was evaporated water was added The produced precipitate was filtered washed with water

実験手順: In an acetic acid (0.37 mL) solvent, a mixture including Compound 97c (78.2 mg, 0.38 mmol), 2-amino-4-chlorobenzenethiol (60.0 mg, 0.38 mmol), and sodium acetate (NaOAc) (93.6 mg, 1.13 mmol) was refluxed for 1 hour. After cooling, the reaction mixture was distributed between ethyl acetate and water, and an organic layer was evaporated under reduced pressure. The produced precipitate was filtered, and washed with methylene chloride to obtain Compound 99 (46.6 mg, 39.6%). was refluxed for 1 hour After cooling an organic layer was evaporated under reduced pressure The produced precipitate was filtered washed with methylene chloride

実験手順: In a DMF (3 mL) solvent, a solution including 2-amino-4-chlorobenzenethiol (100 mg, 0.63 mmol) and 3,5-dibromo-4-hydroxybenzaldehyde (127 mg, 0.63 mmol) was heated at a temperature of 100° C. for 8.5 hours. After DMF was evaporated therefrom, the residual was purified by silica gel column chromatography using hexane and ethyl acetate (5:1) as a developer to obtain a solid Compound 96 (34.3 mg, 18.1%). After DMF was evaporated the residual was purified by silica gel column chromatography

実験手順: 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%). was refluxed for 1 hour After cooling an organic layer was dried filtered evaporated under reduced pressure The resultant residual was added to water the precipitate was filtered the filtered product was washed with water and methylene chloride

実験手順: In an acetic acid (0.6 mL) solvent, a mixture including 2-amino-4-chlorobenzenethiol (100 mg, 0.44 mmol), 3,5-dihydroxybenzaldehyde (60 mg, 0.44 mmol), and sodium acetate (107 mg, 1.30 mmol) was refluxed for 7 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 90 (64.2 mg, 34.7%). was refluxed for 7 hours After cooling an organic layer was dried filtered evaporated under reduced pressure The residual was purified by silica gel column chromatography
