Adding a certain compound to certain chemical reactions, such as: 345637-71-0, name is 2-(5-Methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)acetic acid, 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 345637-71-0, Computed Properties of C7H7F3N2O2
A mixture of 5-[4-[5-(2,6-difluorophenyl)-4,5-dihydro-3-isoxazolyl]-2- thiazolyl]tetrahydro-2H-l,2-oxazine (i.e. the product of Step K) (0.235 g, 0.67 mmol), 5- methyl-3-(trifluoromethyl)-lH-pyrazole-l -acetic acid (0.154 g, 0.74 mmol) and N,N-dicyclohexylcarbodiimide (0.152 g, 0.74 mmol) in dichloromethane was stirred at room temperature for 20 h. The reaction mixture was diluted with more dichloromethane and the urea by-product was removed by filtration. The filtrate was concentrated under reduced pressure to a pale-yellow foam (0.42 g). The resulting foam was dissolved in a minimum amount of dichloromethane and loaded onto a chromatotron plate (2mm) eluting with a gradient of ethyl acetate in dichloromethane to give the title compound, a compound of the present invention, as a colourless foamy solid (0.101 g).in NMR (CDCI3): delta 2.05-2.20 (m, 1H), 2.20-2.35 (m, 4H), 3.403.55 (m, 1H), 3.55-3.70 (m, 2H), 3.75-3.88 (m, 1H), 4.08-4.20 (m, 1H), 4.35-4.45 (m, 1H), 4.45-4.55 (m, 1H), 5.08 (s, 2H), 6.02-6.12 (m, 1H), 6.30 (s, 1H), 6.85-6.98 (m, 2H), 7.25-7.38 (m, 1H), 7.72 (s, 1H).
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-(5-Methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)acetic acid, other downstream synthetic routes, hurry up and to see.
