実験手順

2-Amino-5-bromo-4-methoxybenzoic acid (1.56 g, 6.34 mmol) is dissolved in methanol (15 ml), treated with piperidine (0.063 ml, 0.63 mmol) and 1,3,5-triazine (772 mg, 9.5 mmol) and refluxed for one hour. After cooling to room temperature, the resulting crystals are filtered off with suction and washed with methanol. The desired product is obtained in 63% yield (1.01 g).

後処理
