In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 10010-93-2, name is 3-Methyl-5-(trifluoromethyl)-1H-pyrazole belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. SDS of cas: 10010-93-2
Example 8 Synthesis of 1-[1-(4-fluorophenyl)-6,7-dihydro-5H-pyrazolo[4,3-b]pyridin-4-yl]-2-[5-methyl-3-(trifluoromethyl)pyrazol-1-yl]ethanone 2-Chloro-1-(1-(4-fluorophenyl)-6,7-dihydro-1H-pyrazolo[4,3-b]pyridin-4(5H)-yl)ethanone (118 mg, 0.4 mmol) was diluted in 1.2 mL of 2:1 THF:DMF and treated with K2CO3 (111 mg, 0.8 mmol) and 5-methyl-3-(trifluoromethyl)-1H-pyrazole (60 mg, 0.4 mmol). The slurry was heated to 75 C. for 2 hours. The reaction slurry was purified by normal phase flash chromatography (24 g column, eluting with 10-80% EtOAc in hexanes) to provide 109 mg (67%) of the title compound as a white solid. 1H NMR (400 MHz, CDCl3) delta 8.36 (s, 0.8H), 7.59 (s, 0.2H), 7.42-7.47 (m, 2H), 7.12-7.25 (m, 2H), 5.25 (s, 0.4H), 5.14 (s, 1.6H), 3.92 (m, 0.4H), 3.86 (m, 1.6H), 2.86 (t, J=6.2 Hz, 2H), 2.37 (s, 2.4H), 2.36 (m, 0.6H), 2.11 (m, 1.6H), 2.04 (m, 0.4H); MS: (ES) m/z calculated for C19H18F4N5O [M+H]+ 408.1, found 408.1.
The synthetic route of 10010-93-2 has been constantly updated, and we look forward to future research findings.
