Some common heterocyclic compound, 3641-13-2, name is 5-Amino-4H-1,2,4-triazole-3-carboxylic acid, molecular formula is C3H4N4O2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Recommanded Product: 5-Amino-4H-1,2,4-triazole-3-carboxylic acid
General procedure: A mixture of benzil (0.01 mol), aldehydes (0.01 mol), 3-amino-1,2,4-triazole-5-carboxylic acid (0.01 mol), ammonium acetate (0.01 mol) and ceric ammonium nitrate (15 mol%) as a catalyst were refluxed in ethanol (15 mL) for about 3-4 h. The progress of the reaction was monitored by TLC. After completion of reaction, the mixture was cooled to room temperature. The solid formed was filtered and dried. The crude products were recrystallized by ethanol.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3641-13-2, its application will become more common.
