In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 934-32-7 as follows. COA of Formula: C7H7N3
General procedure: A mixture of 2-aminobenzimidazole (1, 1 mmol), 4-bromobenzaldehyde (2a, 1 mmol), malononitrile (3,1 mmol) and p-TSA (10 mol%) was stirred at 80 8C undersolvent-free conditions for 30 min (Table 3, entry 1). Theprogress of the reaction was monitored by TLC. Aftercompletion of the reaction, the reaction mixture waswashed with water and ethanol, and the residue recrystallizedfrom ethanol to afford the pure product 4a (92%).
According to the analysis of related databases, 934-32-7, the application of this compound in the production field has become more and more popular.
