Reaction Steps

In a DMF (3 mL) solvent, a mixture including 1,2-phenylenediamine (100 mg, 0.92 mmol), 3-bromo-4-hydroxybenzaldehyde (187.8 mg, 0.92 mmol), and Na2S2O5 (177.6 mg, 0.92 mmol) was mixed at a temperature of 80° C. for 1 hour. After cooling, DMF was removed therefrom under reduced pressure. Methylene chloride and water were added thereto to obtain a solid product, and the precipitate was filtered, and the filtered product was washed with methylene chloride, ethyl acetate, and water to obtain a solid Compound 56 (79.4%).
