Reaction Steps
Approximately 80.1 gm (0.6 mole) of tolyltriazole, 200 ml 2-propanol, and 78.0 gm (0.6 mole) diisobutylamine were mixed in a 500 ml reactor until a homogeneous phase was formed. 51.0 gm (0.618 mole) of aqueous formaldehyde was slowly added while maintaining a reactor temperature ≤40° C. Thereafter, the reactants were heated at 82±2° C. for 4 hrs., then at 110±2° C. for two additional hours during which isopropanol and water were removed by distillation. The final product (163.5 gm) is a yellowish liquid which solidifies upon standing at ambient temperature (m.p. 49°-51° C.). A final filtration to remove possibly unreacted tolyltriazole is optional. However, small amounts of residual water could make the final product appear hazy.
