52222-73-8, name is 4-(Trifluoromethyl)-1H-pyrazole, belongs to pyrazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Formula: C4H3F3N2
55 mg of 2-[3-(ethylsulphonyl)-6-fluoropyridin-2-yl]-1-methyl-5-(trifluoromethyl)-1H-benzimidazole (0.14 mmol) were dissolved in 2 ml of acetonitrile. 29 mg (0.21 mmol) of 4-(trifluoromethyl)-1H-pyrazole and 59 mg (0.42 mmol) of potassium carbonate were added and stirred for 3 h at room temperature. The mixture was filtered, concentrated and purified by column chromatography with a cyclohexane/ethyl acetate gradient as mobile phase. log P (neutral): 4.16; MH+: 504; 1H-NMR (400 MHz, D6-DMSO) delta ppm: 9.38 (s, 1H), 8.712 (d, 1H), 8.46 (s, 1H), 8.42 (d, 1H), 8.16 (s, 1H), 7.98 (d, 1H), 7.70 (dd, 1H), 3.906 (q, 2H), 3.90 (s, 3H), 1.24 (t, 3H).
The synthetic route of 52222-73-8 has been constantly updated, and we look forward to future research findings.
