Synthetic Route of 13421-00-6, A common heterocyclic compound, 13421-00-6, name is 5-Chloro-2-iodobenzoic acid, molecular formula is C7H4ClIO2, 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.
Reference Example 2-66 5-Chloro-2-[[1-(2-pyridinyl)-1H-pyrazol-5-yl]amino]benzoic acid Following the procedure described in Reference Example 2-5, the title compound was prepared from 5-chloro-2-iodobenzoic acid and 1-(2-pyridinyl)-1H-pyrazol-5-ylamine (88% yield). mp: 233-234 C. (recrystallized from ethanol). NMR (DMSO-d6) delta: 6.42 (1H, d, J=2.0 Hz), 7.38 (1H, ddd, J=1.2 Hz, 4.8 Hz, 7.4 Hz), 7.54 (1H, dd, J=2.6 Hz, 8.8 Hz), 7.63 (1H, d, J=8.8 Hz), 7.71 (1H, d, J=2.0 Hz), 7.88-7.92 (2H, m), 7.99-8.08 (1H, m), 8.47 (1H, dd, J=0.8 Hz, 1.8 Hz, 4.8 Hz), 12.24 (1H, br s), hidden (1H).
The synthetic route of 13421-00-6 has been constantly updated, and we look forward to future research findings.
