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, To a solution of thiocarbonyldiimidazole (2.1 g, 11.8 mmol) in tetrahydrofuran (30 mL) at room temperature, was added 1,1 -dimethylethyl 1-piperazinecarboxylate (2.0 g, 10.7 mmol). The reaction mixture was stirred at room temperature for 2 h and then heated to 55 C for additional 2 h. The reaction mixture was cooled to room temperature and concentrated under reduced pressure until approximately 20 mL of tetrahydrofuran remained. The residue was then treated with a 2 M solution of ammonia in methanol (10 mL) and stirred at room temperature for 24 h. The reaction mixture was concentrated under reduced pressure, and the residue was triturated with diethyl ether (25 mL) to give a white precipitate. The precipitate was filtered and dried to give 1.5 g of the title compound as a white solid..H NMR (CDCI3) delta 1.39 (s, 9H), 3.32 (m, 4H), 3.73 (m, 4H), 7.49 (br s, 2H).
As the paragraph descriping shows that 57260-71-6 is playing an increasingly important role.
