Related Products of 134227-45-5,Some common heterocyclic compound, 134227-45-5, name is 3,4,5-Trifluorobenzonitrile, molecular formula is C7H2F3N, 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.
Potassium carbonate (1.38 g, 10 mmol) was added to a solution of 2,4-dihydro- 2,5-dimethyl-3H-pyrazol-3-one (0.70 g, 6.3 mmol) in N,N-dimethylformamide (15 mL). 3,4,5-Trifluorobenzonitrile (0.94 g, 6.0 mmol) was added, and the reaction mixture was heated at 75 C under a nitrogen atmosphere for 16 h, then allowed to cool. The reaction mixture was partitioned between water (60 mL) and ethyl acetate (30 mL). The organic phase was washed with water (2 x 30 mL) and brine (30 mL), dried over MgS04, and concentrated to give the title compound as a yellow oil (1.38 g).¾ NMR delta 7.36 (m, 2H), 5.24 (s, 1H), 3.78 (s, 3H), 2.16 (s, 3H).
The synthetic route of 134227-45-5 has been constantly updated, and we look forward to future research findings.
