Adding a certain compound to certain chemical reactions, such as: 309740-49-6, name is Methyl 1-methyl-4-nitro-1H-pyrazole-5-carboxylate, belongs to pyrazoles-derivatives 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 309740-49-6, Recommanded Product: Methyl 1-methyl-4-nitro-1H-pyrazole-5-carboxylate
(3) Compound(1)(17.0 g) was added to 28% ammonia water(285 mL) and the mixture was stirred at 60C for 6 hours. After standing to cool, the reaction solution was concentrated under reduced pressure to give Compound(2)(16.0 g) as a colorless solid. ESI-MS(m/e):169[M-H]-.
