A common heterocyclic compound, the phthalazine compound, name is 4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one,cas is 763111-47-3, mainly used in chemical industry, its synthesis route is as follows.,763111-47-3
To 20 mg (54.5 muiotaetaomicronIota) of 4-(4-fluoro-3-(piperazine-l-carbonyl)benzyl)phthalazin-l(2H)-one dissolved in 1 mL of MeCN, 9.2 mg (65.5 muiotaetaomicronIota) 4-fluorobenzoic acid was added followed by 24.8 mg (65.5 muiotaetaomicronIota) of HBTU and 18 mu (131 muiotaetaomicronIota) of Et3N. The reaction mixture was stirred for 5 minutes and purified by H PLC to yield the compound as an orange solid (11.5 mg, 23.5 muiotaetaomicronIota, 43%). 1H-NM R (500 M Hz, CDC delta = 10.74 (s, 1H), 8.51-8.49 (d, 1H), 7.83-7.76 (m, 2H), 7.82 (s, 1H), 7.45-7.44 (m, 2H), 7.38-7.36 (m, 2H), 7.14-7.08 (m, 3H), 4.33 (s, 2H), 3.75-3.39 (m, 8H). MS-ES m/z [M + Na]+ = 511.2. H RMS-ESi m/z calculated for [C27 H22 N4 03 F2 Naf 511.1558, found 511.1569 [M + Na]+.
As the rapid development of chemical substances, we look forward to future research findings about 763111-47-3
