The synthetic route of 10010-93-2 has been constantly updated, and we look forward to future research findings.
Synthetic Route of 10010-93-2, A common heterocyclic compound, 10010-93-2, name is 3-Methyl-5-(trifluoromethyl)-1H-pyrazole, molecular formula is C5H5F3N2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
[00143] Step 1: A mixture of 2-chloro-l-(l-(4-chloro-3-methoxyphenyl)piperidin- 4-yl)ethanone (580 mg, 1.919 mmol; see Example Ia, Step 2), 5-methyl-3- (trifluoromethyl)-lH-pyrazole (576 mg, 3.84 mmol), potassium carbonate (796 mg, 5.76 mmol) and acetonitrile (20 mL) was stirred at RT for 12 h. After this time, the solvent was removed under reduced pressure and the resultant residue was partitioned between EtOAc (10OmL) and water (50 mL). The organic phase was washed with brine, dried (TS^SO4) and concentrated on a rotary evaporator to yield a residue. The residue was purified by flash chromatography using a 40 g silica gel cartridge and gradient elution from 10: 1 Hex/EtOAc to 1 : 1 Hex/EtOAc. The fractions containing the product were pooled and concentrated on a rotary evaporator to give l-(l-(4- chloro-3-methoxyphenyl)piperidin-4-yl)-2-(5-methyl-3-(trifluoromethyl)-lH-pyrazol- l-yl)ethanone (650 mg, 1.563 mmol, 81 % yield) as clear oil. 1H-NMR (400 MHz, CDCl3) delta ppm 7.19 (1 H, d, J=8.57 Hz), 6.49 (1 H, d, J=2.42 Hz), 6.44 (1 H, dd, J=8.68, 2.53 Hz), 6.35 (1 H, s), 5.01 – 5.04 (2 H, m), 3.84 – 3.89 (3 H, m), 3.62 – 3.69 (2 H, m), 2.77 (2 H, td, J=12.03, 2.75 Hz), 2.58 (1 H, tt, J=I 1.29, 3.87 Hz), 2.21 (3 H, s), 1.99 (2 H, s), 1.80 – 1.91 (2 H, m).
