Adding a certain compound to certain chemical reactions, such as: 332-48-9, name is 1-(2-Bromoethoxy)-4-fluorobenzene, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 332-48-9, Computed Properties of C8H8BrFO
EXAMPLE 49 1-(2-(4-Fluorophenoxy)ethyl)-2-(hydroxymethyl)piperidine hydrobromide From 2-hydroxymethylpiperidine (500 mg, 4.34 mmol) and 2-(4-fluorophenoxy)ethyl bromide (999 mg, 4.56 mmol) there was obtained a colorless oil (970 mg, 88%): 1H NMR (CDCl3) d 1.60-2.11 (m, 6 H), 2.67-3.59 (m, 6 H), 3.80 (dd, J1=11 Hz, J2=3.9 Hz, 1 H), 4.15 (dd, J, =11 Hz, J2=3.9 Hz, 1 H) 4.37-4.42 (m, 2 H), 7.13-7.35 (m, 4 H). The hydrobromide was obtained as a colorless powder (1.08 g, 96%): mp 103.5-105.5 C.; Anal. Calcd for C14H21BrFNO2: C, 50.31; H, 6.33; N, 4.19. Found: C, 50.39; H, 6.15; N, 3.99.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1-(2-Bromoethoxy)-4-fluorobenzene, and friends who are interested can also refer to it.
