Adding a certain compound to certain chemical reactions, such as: 19848-54-5, name is 2-Hydrazinyl-3-methylpyrazine, belongs to pyrazines 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 19848-54-5, Formula: C5H8N4
Step B. lV1-(3-Methylpyrazin-2-yl)-222-trifluoroacetohydrazide; To 1.6 g (12.9 mmol) of the product from Step A at 0 C was added slowly and with vigorous stirring 16 mL of trifluoroacetic anhydride that had been cooled to 0 C. The resultant mixture was stirred at ambient temperature for 1 h, concentrated in vacuo, and made basic by treatment with methanolic ammonia. The residue was purified by column chromatography (silica gel, 5% methanol/0.5% ammonium hydroxide/dichloromethane) to give 2.83 g (100%) of the title compound. MS 221 (M+1).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Hydrazinyl-3-methylpyrazine, other downstream synthetic routes, hurry up and to see.
