24566-79-8, name is N-(6-Bromohexyl)phthalimide, belongs to indolines-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Recommanded Product: N-(6-Bromohexyl)phthalimide
2-[6-(4-phenyl-1-piperidinyl)hexyl]-1H-isoindole-1,3(2H)-dione: To the 500 ml RB-flask was added 4-phenylpiperidine hydrochloride (5 g, 25 mmol), N-(6-bromohexyl)phthalimide (15.5 g, 50 mmol), N,N-diisopropylethylamine (21.8 ml, 125 mmol), tetrabutylammonium iodide (0.2 g), and dioxane (250 ml) at room temperature. The reaction mixture was stirred at 100 oC for 72 h. The solvent was removed in vacuo and the crude product was purified by flash chromatography (98:2=Chloroform: 2N ammonia in methanol) to afford 7.67 g of the desired product (77% yield): 1H NMR (400 MHz, CDCl3) delta 7.78-7.79 (m, 2H), 7.74-7.65 (m, 2H), 7.32-7.14 (m, 5H), 3.69 (t, 2H, J=7.35 Hz), 3.06 (d, 2H, J=11.0 Hz), 2.49 (quintet, 1H, J=7.6 Hz), 2.36 (t, 2H, J=7.6 Hz), 2.02 (t, 2H, J=12.5 Hz), 1.82 (br s, 4H), 1.69 (t, 2H, J=6.3 Hz), 1.54 (br s, 2H), 1.37 (br s, 4H); ESMS m/e: 391.3 (M+H) +; Anal. Calc. for C25H30N2O2+0.2H2O: C, 76.19; H, 7.77; N, 7.11. Found: C, 76.14; H, 7.38; N, 7.13.
The synthetic route of 24566-79-8 has been constantly updated, and we look forward to future research findings.
