22 Sep 2021 News Simple exploration of tert-Butyl piperazine-1-carboxylate

The synthetic route of 57260-71-6 has been constantly updated, and we look forward to future research findings.

57260-71-6,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.57260-71-6,tert-Butyl piperazine-1-carboxylate,as a common compound, the synthetic route is as follows.

A mixture of 4-iodoaniline (0.654 g, 3 mmol), piperazine-1-carboxylic acid tert-bvyl ester (0.67 g, 3.6 mmol), potassium phosphate (1.272 g, 6 mmol), ethylene glycol (0.33 ml) and copper iodide (0.03 g, 0.15 mmol) in 2-propanol (3 ml) was placed under argon in a sealed-tube and heated to 8O0C for 30 hours. After being cooled to room temperature, the medium was washed with water (50 ml) and extracted with ethyl acetate (100 ml). The organic layer was dried over MgSO4, concentrated and chromatographed (dichloromethane: acetone, 70:30) to yield 43a (0.36 g, 1.3 mmol, 43%) as a yellow powder.

The synthetic route of 57260-71-6 has been constantly updated, and we look forward to future research findings.

57260-71-6, General procedure: 1-Boc-piperazine (150 mg, 0.81 mmoles) was dissolved in anhydrous DMF (2 mL) and, under stirring, DIPEA (303 mL, 1.78 mmoles), PyBOP (461 mg, 0.89 mmoles) and 2-thiophenecarboxylic acid (114 mg, 0.89 mmoles) were added at room temperature. After complete conversion of 1-Boc-piperazine monitored by TLC analysis, the solution was diluted with DCM and washed with NaOH 0.5M, brine, HCl 0.1M and brine. Organic phase was dried over Na2SO4, filtered and concentrated under reduced pressure. The crude product was purified by chromatographic column (eluent DCM/MeOH = 96/4) to obtain 10e (188 mg, 79% yield).
