57260-71-6, tert-Butyl piperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
57260-71-6, The compound 1-tert-butoxycarbonyl piperazine (0.6g, 3.2mmol) and triethylamine (4.6mL, 32mmol) wasdissolved in dry tetrahydrofuran (10 mL), at room temperature, to this solution was added dropwisetrimethylsilyl isocyanate (4.2mL, 32mmol), stirred at rt for 1.5h, ice Water (10 mL), tetrahydrofuran spin, theaqueous phase with ethyl acetate (30mL ¡Á 3). The organic phase was dried over anhydrous Na 2 SO 4, removeThe solvent was concentrated and solid was washed with ethyl acetate (2mL) ultrasonic cleaning 1min, suctionfiltration, to give 0.3g white solid: 4-carbamoyl-piperazine 1-carboxylate, yield: 40%.
As the paragraph descriping shows that 57260-71-6 is playing an increasingly important role.
