The synthetic route is as follows., 22884-10-2
48.87 g (0.4 mol) of 3,4-diaminotoluene and 63.05 g (0.5 mol) of 1-imidazole-1-acetic acid were weighed into a 1000 mL three-necked flask and 375 mL of 4 mol / L hydrochloric acid was added The mixture was stirred for 20 h at room temperature. The solution was reddish-brown and then refluxed at 100 C for 15 h. The solution gradually deepened and finally dark brown. After cooling, the reaction solution was poured into 1000 mL of distilled water and adjusted to pH 7-8 with ammonia. A large amount of precipitate was collected, suction filtered and then recrystallized from hot water to obtain 33.02 g of yellow crystals (yield: 38.89%).
