Adding a certain compound to certain chemical reactions, such as: 52867-42-2, name is Methyl 2-methyl-5-oxo-2,5-dihydro-1H-pyrazole-3-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 52867-42-2, Product Details of 52867-42-2<\/a><\/p>\n

Methyl-3-(difluoromethoxy)-1-methyl-1H-pyrazole-5-carboxylate A solution of 2.00 g (12.8 mmol) of methyl 3-hydroxy-1-methyl-1H-pyrazole-5-carboxylate (preparation: Chem. Ber. 1974, 107, 1318-1328) in 28 ml of N,N-dimethylformamide is admixed with 5.09 g (32.0 mmol, 96%) of chlorodifluoroacetic acid sodium salt and 2.66 g (19.2 mmol) of potassium carbonate, and the reaction mixture is heated at 80 C. overnight. The reaction mixture is added to 300 ml of water and extracted several times with ethyl acetate. The organic phase is dried over magnesium sulphate, filtered and concentrated by evaporation in vacuo on a rotary evaporator. Chromatographic purification gives 1.07 g of methyl-3-(difluoromethoxy)-1-methyl-1H-pyrazole-5-carboxylate (40%). 1H-NMR (400 MHz, d6-DMSO): delta=7.19 (t, 1H), 6.55 (s, 1H), 4.00 (s, 3H), 3.55 (s, 3H) ppm. HPLC-MS: log P=2.04; mass (m\/z)=207 [M+H]+.<\/p>\n

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, Methyl 2-methyl-5-oxo-2,5-dihydro-1H-pyrazole-3-carboxylate, other downstream synthetic routes, hurry up and to see.<\/p>\n
