Reference of 101335-11-9, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 101335-11-9, name is 2-Chloro-4-fluoro-1-iodobenzene, This compound has unique chemical properties. The synthetic route is as follows.
Step 2: (E)-4-(2-(2-Chloro-4-fluorophenyl)-l-(4-(thiazol-5-yl)phenyl)but-l-en-l- yl)benzaldehyde[00394] A mixture of (Z)-4-(2-(4,4,5,5-tetramethyl-l,3,2-dioxaborolan-2-yl)-l-(4-(thiazol-5- yl)phenyl)but-l-en-l-yl)benzaldehyde (99 mg, 0.22 mmol), 2-chloro-4-fluoro-l-iodobenzene (114 mg, 0.44 mmol), Pd(PPh3)2Cl2(15 mg, 0.022 mmol), and KOH (6M, 0.2 mL, 1.32 mmol) in 1,4-dioxane (2.2 mL) was heated to 90C overnight. After cooling, ethyl acetate and brine were added to the reaction mixture and the two layers were separated. The organic layer was washed with more brine, dried over sodium sulfate, filtered and evaporated to dryness. The residue was purified by flash chromatography on silica gel to afford 68 mg of a mixture of the title compound (major) and the undesired regioisomer (minor). 1H NMR (400 MHz, DMSO-d6) of major: delta 9.84 (s, 1H), 9.11 (s, 1H), 8.35 (s, 1H), 7.75 (d, 2H), 7.64 (d, 2H), 7.40-7.33 (m, 4H), 7.17 (m, 3H), 2.45 (q, 2H), 0.93 (t, 3H).
The chemical industry reduces the impact on the environment during synthesis 2-Chloro-4-fluoro-1-iodobenzene. I believe this compound will play a more active role in future production and life.
