Reaction Steps

2.50 g of 2-bromo-1-methanesulfonylaminobenzene was added to a solution containing 1.52 g of DBU, 85 g of cupric chloride dihydrate, and 90 mg of 1,10-phenanthroline in 40 ml of methanol, and the mixture was heated under reflux for 5 hours. After the temperature was brought to room temperature, the reaction mixture was treated in a usual manner, and crystallization was effected from n-hexane/ethyl acetate, to produce 1.64 g (yield: 82%) of the desired compound.
