実験手順

2-Amino-4-methoxybenzonitrile (4.47 g, 30.2 mmol) is dissolved in 70 ml of dioxane and treated at 0° C. with bromine (1.71 ml, 33.2 mmol). It is subsequently stirred at 0° C. for one hour. After addition of diethyl ether, the resulting crystals are filtered off with suction. The desired product is obtained in 81% yield (5.52 g).
