763111-47-3, 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. 4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one, cas is 763111-47-3,the phthalazine compound, it is a common compound, a new synthetic route is introduced below.
EXAMPLE A.6. Compound c-5 (127l): 4-(4-fluoro-3-(4-(3-(3-iodophenyl)propanoyl)piperazine-1-carbonyl)benzyl)phthalazin-l(2H)-one. A solution of 4-(4-fluoro-3-(piperazine-l-carbonyl)benzyl)phthalazin-l(2H)-one (10 mg, 0.0275 mmol), HBTU (16 mg, 0.0413 mmol) triethylamine (40 mu, 0.3 mmol) and 3-(3-iodophenyl)propionic acid (7.6 mg, 0.0275 mmol) in 400 mu of acetonitrile was stirred overnight at room temperature. The crude product was then purified by preparative HPLC and the isolated product dried at vacuum to obtain a white solid (5.1 mg, 38%). 1H NMR (CDCI3) delta = 10.33 (s, 1H), 8.41-8.39 (d, 1H), 7.71-7.63 (m, 3H), 7.51-7.45 (m, 2H), 7.27-7.25 (m, 2H), 7.12-6.92 (m, 3H), 4.22 (s, 2H), 3.65-3.12 (m, 8H), 2.88- 2.83 (m, 2H), 2.59-2.48 (m, 2H). LC-ESI-MS (+) m/z = 647.1 [M+Na+]+. HRMS-ESI [M+H+]+ m/z calculated for [C29H26FIN403 625.1112, found 625.1111.
The chemical industry reduces the impact on the environment during synthesis,763111-47-3,4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one,I believe this compound will play a more active role in future production and life.
