4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one, cas is 763111-47-3, it is a common heterocyclic compound, the phthalazine compound, its synthesis route is as follows.,763111-47-3
4-[4-fluoro-3-(piperazin-1 -ylcarbonyl) benzyl] phthalazin-1 (2H)-one (IX) (40.0 g, 0.1 1 mol) and 1 H-benzotriazol-1 -yl(cyclopropyl)methanone (X) (26 g, 0.14 mol) were stirred in acetonitrile (320 mL) and the progress of reaction was monitored by HPLC. After completion of reaction, the resulted precipitate was filtered and washed with acetonitrile (40.0 mL) then dried to afford Olaparib (I) as a white to off- white solid. The PXRD pattern of Olaparib thus obtained matches with Form-A as illustrated in figure-3. (Yield: 90%, HPLC purity: 99.99%)
With the rapid development of chemical substances, we look forward to future research findings about 4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one
