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. 332-48-9, name is 1-(2-Bromoethoxy)-4-fluorobenzene, A new synthetic method of this compound is introduced below., Computed Properties of C8H8BrFO
Step 1. 5-[2-(4-fluoro-phenoxy)-ethoxy]-tricyclo[8.2.1.03,8]trideca-3(8),4,6-trien-13-one A mixture of 2-hydroxy-5,6,7,8,9,10-hexahydro-6,9-methanobenzo[a][8]annulen-11-one (21.7 g; J. Org. Chem 1982, 47, 4329), K2CO3 (17.7 g) and 1-(2-Bromo-ethoxy)-4-fluoro-benzene (40.3 g) in DMF (400 ml) were stirred for 72 hours at 120 C. The reaction was then cooled to room temperature and the solvent removed in vacuo. The residue was then washed with saturated NaHCO3 solution and the organics extracted with EtOAc (3*200 ml). The organics were then combined, dried (MgSO4) and the solvent removed in vacuo yielding a dark brown oil which was purified by flash chromatography on silica eluding 20% EtOAc in isohexane giving the title alkylated ketone (15.97 g, 44%). MS (ES+) 341 [M+H]+.
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.
