Then, 2.14 g of the 2-bromo-1-acetylaminobenzene was added to a solution containing 2.3 ml of a 28% methanol solution of sodium methoxide, 100 mg of cuprous chloride, and 145 mg of 8-hydroxyquinoline in 40 ml of methanol, and the mixture was heated under reflux for 50 minutes. After cooling with water, ethyl acetate was added thereto, and the resulting mixture was washed with water and dried over Glauber's salt. The solvent was distilled off, and the obtained crude crystals were recrystallized from an n-hexane/ethyl acetate solvent mixture, to obtain 1.56 g (yield: 95%) of the desired compound. The spectrum data of the compound was in agreement with the spectrum data of the separately synthesized reference compound.
