4318-42-7, 1-Isopropylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Preparation of 3-(4-Isopropylpiperazin-1-yl)benzaldehyde (3): A mixture of 2-(3-bromophenyl)-1,3-dioxane (2, 1.58 g, 6.5 mmol), 1-isopropylpiperazine (1.0 g, 7.8 mmol), rac-BINAP (60 mg, 0.096 mmol), and tert-BuONa (1.06 g, 11.1 mmol) in toluene (15 mL) was degassed under vacuum and flushed with nitrogen. Pd2(dba)3 (30 mg, 0.033 mmol) was added. The reaction mixture was degassed again and flushed with nitrogen and was heated at 100¡ã C. under nitrogen for 16 h. The reaction mixture was poured into cold 1N HCl (30 mL) and stirred for 2 h. It was adjusted to pH 8 with 6N NaOH and extracted with EtOAc (3*50 mL). The combined organic layers were dried (MgSO4), filtered, concentrated, and purified by silica gel chromatography eluting with 0-100percent EtOAc (containing 5percent v/v Et3N) in hexanes to afford the title compound as a viscous yellow oil (1.32 g, 87percent): 1H NMR (500 MHz, CDCl3) delta 9.96 (s, 1H), 7.44-7.37 (m, 2H), 7.34-7.30 (m, 1H), 7.21-7.16 (m, 1H), 3.28 (t, J=5.0 Hz, 4H), 2.73 (sept, J=6.5 Hz, 1H), 2.69 (t, J=5.0 Hz, 4H), 1.10 (d, J=6.5 Hz, 6H); ESI MS m/z 233 [M+H]+.
4318-42-7, The synthetic route of 4318-42-7 has been constantly updated, and we look forward to future research findings.
