With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4318-42-7,1-Isopropylpiperazine,as a common compound, the synthetic route is as follows.
General procedure: A mixture of the intermediates 3a-3e (5 mmol) and corresponding secondary amine 4a-4g (5.5 mmol) was added in CH3CN (20 ml) at the presence of anhydrous K2CO3 (6 mmol). The mixture was heated at 65 ¡ãC for 6-10 h. The solvent was evaporated in vacuo. The residue was dissolved in CH2Cl2 (25 mL), washed with water (20 mL ¡Á 3), and the combined organic phases were washed with saturated aqueous NaCl (30 mL), dried over sodium sulfate, and filtered. The solvent was evaporated under reduced pressure. The residue was purified on a silica gel chromatography using mixtures of petroleum/acetone as eluent to get the target products TM-1~TM-28.
4318-42-7, The synthetic route of 4318-42-7 has been constantly updated, and we look forward to future research findings.
