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.
Glutaric anhydride (0.50 g, 4.37 mmol) and N,Ndiisopropylethylamine (2.28 mL, 13.11 mmol) were added to a solution of 4-[[4-Fluoro-3-(piperazine-1-carbonyl)phenyl]methyl]-2H-phthalazin-1-one (2) (1.60 g, 4.37 mmol) in dichloromethane (50 mL) and the reaction mixture and stirred for 30 minutes. Water (50 mL) was then added and the reaction mixture stirred for another 30 minutes. The reaction mixture was acidified with HCl to pH 2, the organic phase separated and the aqueous phase extracted with dichloromethane (3*30 mL). The combined organic phases were dried over MgSO4 and volatiles removed in vacuo. The resulting crude material was purified using silica chromatography (0%-30% MeOH/DCM), yielding the pure product as an off-white solid (1.52 g, 3.16 mmol, 72%).
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.
