Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 109-08-0, name is 2-Methylpyrazine, A new synthetic method of this compound is introduced below., Computed Properties of C5H6N2
General procedure: Reaction of AgNO3 (33.8 mg, 0.2 mmol), methylpyrazine (mpyz)(19 mg, 0.2 mmol) and isophthalic acid (H2ipa) (33.3 mg, 0.2 mmol) took place in methanol-DMF (DMF = N,N-dimethylformamide) solvents (6 ml, v/v = 1:1) under ultrasonic treatment (160 W, 40 KHz,30 min) at 50 ¡ãC. Addition of ammonia (25percent, 0.5 mL) was found to be an efficient way to eliminate the white precipitate. The resultant solution was allowed slowly and quietly to evaporate at room temperature. The pale pink and prismatic crystals of compound 1 are obtained after several days in the darkness. The crystals were isolated by filtration and washed by deionized water and enthanol and dried in the air.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
