Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 13421-00-6, name is 5-Chloro-2-iodobenzoic acid, A new synthetic method of this compound is introduced below., Recommanded Product: 13421-00-6
Production example 15 5-Chloro-2-[[1-(2-pyridinyl)-1H-pyrazol-5-yl]amino]benzoic acid Following the procedure described in Production Example 7, the title compound was prepared from 5-chloro-2-iodobenzoic acid and 1-(2-pyridinyl)-1H-pyrazol-5-ylamine (88% yield). mp: 233-234C (recrystallized from ethanol). NMR (DMSO-d6) delta: 6.42 (1H, d, J=2.0Hz), 7.38 (1H, ddd, J=1.2Hz, 4.8Hz, 7.4Hz), 7.54 (1H, dd, J=2.6Hz, 8.8Hz), 7.63 (1H, d, J=8.8Hz), 7.71 (1H, d, J=2.0Hz), 7.88-7.92 (2H, m), 7.99-8.08 (1H, m), 8.47 (1H, dd, J=0.8Hz, 1.8Hz, 4.8Hz), 12.24 (1H, br s), hidden (1H).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
