27561-62-2, Cyclohexyl(piperazin-1-yl)methanone is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
4-[4-(4-Cyclohexanecarbonyl-piperazine-1-carhonyl)-pyridin-2-ylmethyl-2H-phthalazin-1-one (5)To a stirred solution of 2-(4-oxo-3,4-dihydro-phthalazin-1-ylmethyl)-isonicotinic acid (iva)(0.25g, 0.89mol) in diemthylacetamide (2mL) was added cyclohexyl-piperazin-1-yl-methanone (0.20g, LOmmol) followed by HBTU (0.38g, LOmmol) and diisopropyl ethyl amine (0.35mL, 20.0 mmol) and stirred. The reaction mixture was then concentrated in vacuo and resulting oil subjected to flash chromatography eluent 9:1 EtOAc / MeOH. (rf of 0.3) The titledcompound was isolated as a white solid. Single peak in LC-MS analysis, (0.18g, 56%); m/z (LC-MS, ESP), RT=4.07mins, (M+H)=460; 1H NMR (300 MHz) 12.57 (1H, S -NH), 8.56 (1H, d, J 5.1 Hz), 8.26 (1H, dd, J 1.5, 8.1Hz), 7.95- 7.80 (3H, m), 7.38 (1H, S), 7.25 (1H, d, J 5.7Hz), 4.51 (2H, S), 3.56-3.17 (8H, m), 2.58 (1H, m), 1.71-1.61 (5H, m), 1.38-1.22 (5H, m).
27561-62-2, The synthetic route of 27561-62-2 has been constantly updated, and we look forward to future research findings.
