With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.109-07-9,2-Methylpiperazine,as a common compound, the synthetic route is as follows.
To a solution of 2-methylpiperazine (2.2 g) in tetrahydrofuran (15 ml) was added di-tert-butyl dicarbonate (4.0 g) slowly under ice-cooling, and the mixture was stirred at room temperature for 3.5 hours. Then the reaction mixture was diluted with ethyl acetate (20 ml), washed successively with water and brine, and dried over magnesium sulfate. The solvent was evaporated to give the title compound as a colorless oil. The obtained compound was used for the next step without further purification. [00318] 1H-NMR (300 MHz, CDCl3) delta 1.04 (d, J=5 Hz, 3H), 1.45 (s, 9H), 2.40 (br, 1H), 2.65-2.86 (m, 4H), 2.88-3.08 (m, 1H), 3.75-4.15(m, 2H)., 109-07-9
109-07-9 2-Methylpiperazine 66057, apiperazines compound, is more and more widely used in various fields.
