The important role of

Reference of 6529-53-9, The chemical industry reduces the impact on the environment during synthesis 6529-53-9, name is 1-(2-Bromoethyl)-4-chlorobenzene, I believe this compound will play a more active role in future production and life.

Example 1.49: Preparation of (4-Chloro-l-methyl-lH-pyrazol-3-yl)-{4-[2-(4- chlorophenyl)-ethyl]-piperazin-l-yl}-methanone (Compound 44). In a heavy-walled sealed tube, (4-chloro-l-methyl-lH-pyrazol-3-yl)(piperazin-l- yl)methanone dihydrochloride (27 mg, 0.10 mmol) was dissolved in DMF (1.0 mL). 4- Chlorophenethyl bromide (12 mg, 0.083 mmol) and potassium carbonate (35 mg, 2.5 mmol) were added. The reaction was heated under microwave irradiation for 10 min at 100 C. The solids were filtered and the filtrate was purified by preparative HPLC. The best fractions were lyophilized to afford the TFA salt of the title compound (15 mg) as a white solid. 1H NMR (DMSO-d6, 400 MHz) delta 2.96-3.03 (m, 2H), 3.03-3.28 (m, 2H), 3.30-3.75 (m, 6H), 3.87 (s 3H), 4.23-4.40 (bs, IH), 4.46-4.65 (bs, IH), 7.32 (d, J = 8.4 Hz, 2H), 7.43 (d, J = 8.3 Hz, 2H), 8.10 (s, IH). Exact mass calculated for Ci7H20Cl2N4O: 366.1; Found: LCMS m/z (%) = 367.4 (M+H+ 35Cl, 100%), 369.4 (M+H+ 37Cl, 64%).

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-(2-Bromoethyl)-4-chlorobenzene, other downstream synthetic routes, hurry up and to see.
