In the next few decades, the world population will flourish. 763111-47-3.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.
To the reaction kettle was added 6 L of dichloromethane,4- (4-fluoro-3- (piperazine-1-carbonyl) benzyl) phthalazin-1 (2-hydro) -one (400 g, 1.09 mol)Cooled to 0 C,Triethylamine (153 g, 210 mL, 1.51 mol) was slowly added,Cyclopropanecarbonyl chloride (130 g, 1.24 mol)Stir at room temperature,After TLC detection reaction,Add 3L of water,2L dichloromethane,Dispensing,The organic phase was removed by distillation under reduced pressure,To obtain 320 g of a yellow solid;HPLC purity 96.13%Yield 67.5%.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one, 763111-47-3
