122323-88-0, Methyl piperazine-2-carboxylate dihydrochloride is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Methyl 2-piperazine carboxylate dihydrochloride (20 g, 87 mmol) was suspended in tetrahydrofuran (300 mL), diisopropylethylamine (22 g, 0.17 mmol) was added thereto, and the mixture was stirred at room temperature for 1 hour. Next, a 2.0 M solution of phenylmagnesium bromide in tetrahydrofuran (260 mL, 0.52 mol) was added dropwise over 30 minutes, and the mixture was stirred at room temperature for 14 hours. The reaction solution was ice cooled, water (400 mL) was then added dropwise thereto, and the mixture was stirred for 30 minutes with ice cooling. Di-tert-butyl dicarbonate (13 g, 61 mmol) was added dropwise thereto, and the mixture was stirred at room temperature for 30 minutes. To the reaction solution was added an aqueous saturated ammonium chloride solution, and the resulting mixture was extracted with ethyl acetate. The extract was washed with water, and then concentrated under reduced pressure. The residue was purified with silica gel column chromatography (hexane: ethyl acetate = 3: 1) to obtain the title compound (9.7 g, yield 30%).
122323-88-0, The synthetic route of 122323-88-0 has been constantly updated, and we look forward to future research findings.
