Some tips on 14862-52-3

The synthetic route of 14862-52-3 has been constantly updated, and we look forward to future research findings.

Reference of 14862-52-3, A common heterocyclic compound, 14862-52-3, name is 3,5-Dibromochlorobenzene, molecular formula is C6H3Br2Cl, 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.

3 -Bromo-5 -chlorophenvDmethylformamide l,3-Dibromo-5-chlorobenzene (1.0 g, 3.7 mmol), N-methylformamide (0.26 mL, 4.4 mmol), CuI (35 mg, 0.02 mmol), N,N’-dimethyl ethylenediamine (0.04 mL, 0.37 mmol) and K2CO3 (1.02 g, 7.4 mmol) in 1,4-dioxane (4 mL) were heated to 110 0C in a sealed tube for 20 h. The blue slurry was diluted with EtOAc (10 mL) and filtered through a short silica plug that was washed with several portions of EtOAc. The solvent was removed by evaporation and the resulting yellow oil was purified by flash chromatography using 70 g silica and a gradient of 0%EtOAc to 50%EtO Ac/Heptane. The subtitle compound was obtained as a colourless solid (385 mg, 41%).1H-NMR (CDCl3): delta 8.52 (IH, s), 7.43 (IH, t), 7.24 (IH, t), 7.13 (IH, t), 3.30 (3H, s); GC-MS m/z: 247/249/251 [M+].

The synthetic route of 14862-52-3 has been constantly updated, and we look forward to future research findings.
