21043-40-3, 1-Cyclopentylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
EXAMPLE 511A 3-(4-cyclopentyl-1-piperazinyl)-1-propanamine A mixture of N-(3-bromopropyl)phthalimide (0.8 g, 3.0 mmol), 1-cyclopentylpiperazine (0.46 g, 3.0 mmol), and K2CO3 (1.66 g, 12.0 mmol) in CH3CN (30 mL) was heated to reflux for 3 hours, cooled to room temperature, and filtered through diatomaceous earth (Celite). The filtrate was concentrated, treated with 6N HCl (9.0 mL) and acetic acid (18.0 mL), heated to reflux overnight, and concentrated. The residue was treated with potassium carbonate (1.66 g) in CH3CN (30 mL) for 1 hour. After filtration of the solid, the solvent was evaporated to provide the desired product. MS (DCI/NH3) m/e 212 (M+H)+; 1H NMR (300 MHz, DMSO-d6) delta 8.04 (br s, 2H), 3.68 (m, 4H), 3.41 (m, 4H), 3.21 (m, 2H), 2.91 (m, 2H), 2.0 (m, 4H), 1.84-1.73 (m, 4H), 1.55 (m, 2H).
21043-40-3, The synthetic route of 21043-40-3 has been constantly updated, and we look forward to future research findings.
