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, 1-Propanephosphonic acid cyclic anhydride (10.94mmol, 6.51 mL, 6.96g, 50% solution in ethyl acetate) was added to a stirred solution of 4-aminobenzoic acid (7.29 mmol, 1g), tert-butyl piperazine-1-carboxylate (7.29mmol, 1.358g) and triethylamine (14.58mmol, 1.969mL, 1.473g) in dichloromethane (3OmL). The reaction mixture was stirred for 5 hours, then was washed with sodium bicarbonate and filtered through silica, eluting with ethyl acetate. Evaporation of solvent afforded the title compound (1.53g). 1H NMR (MeOD, 400 MHz):delta 1.4 (9H, s), 3.4 (4H, m), 3.6 (4H, m), 6.7 (1 H, m), 7.2 (2H, m)
The synthetic route of 57260-71-6 has been constantly updated, and we look forward to future research findings.
