Adding a certain compound to certain chemical reactions, such as: 90-16-4, name is Benzo[d][1,2,3]triazin-4(3H)-one, belongs to amides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 90-16-4, Product Details of 90-16-4
Place benzotriazinone (1g) and 1,4-dioxane (10mL) in a 100mL three-necked flask and stir. After warming to 50 C, a 35% formaldehyde solution (7mL) is added dropwise. The temperature of the reaction system was raised to 80 C, and the reaction was completed in 5 hours. Dichloromethane extraction, desolvation, recrystallization from anhydrous methanol gave a white solid with a yield of 62%.
