Application of 332-48-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 332-48-9, name is 1-(2-Bromoethoxy)-4-fluorobenzene belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
EXAMPLE 116 1-(2-(4-Fluorophenoxy)ethyl)-4-(4-methylbenzyl)piperidine hydrochloride STR152 From a mixture of 4-(4-methylbenzyl)piperidine (500 mg, 2.21 mmol), 2-(4-fluorophenoxy)ethyl bromide (508 mg, 2.32 mmol) and K2 CO3 (626 mg, 4.53 mmol) in CH3 CN (20 mL) was obtained the title compound as colorless plates (293 mg, 63%), mp 189-191 C., 1 H NMR (CDCl3) 1.60-2.12 (m, 5H), 2.31 (s, 3H), 2.57 (d, J=7.2 Hz, 2H), 2.62-2.82 (m, 2H), 3.20-3.55 (m, 2H), 3.65 (d, J=12 Hz, 2H), 4.51 (t, J=4.5 Hz, 2H), 6.78-6.84 (m, 2H), 6.92-7.02 (m, 6H), 7.08 (d, J=8.1 Hz, 2H), 12.56 (bs, 1H); Anal. Calcd for C21 H27 ClFNO: C, 69.31; H, 7.48; N, 3.85. Found: C, 69.49; H, 7.39; N, 3.88.
The synthetic route of 1-(2-Bromoethoxy)-4-fluorobenzene has been constantly updated, and we look forward to future research findings.
