反应详情

A mixture of 2-amino-2-methyl-propan-1-ol (2.0 mL, 20.4 mmol), acetanhydride (1.9 mL, 20.4 mmol) and NaHCO3 (2.6 g, 30.6 mmol) in H2O (20 mL) is stirred at RT for 16 h. For workup 1N HCl is added and the mixture is extracted with ethyl acetate. Drying (Na2SO4) of the combined extracts, filtration and evaporation of the solvent yields the title compound as a colorless solid. MS (LC-MS): [M+H]+=132.2. tR (HPLC, Waters Symmetry C18 column, 20-95% CH3CN/H2O/3.5 min, 95% CH3CN/H2O, 2 min, CH3CN and H2O containing 0.1% TFA, flow: 0.6 mL/min): 0.38 min.
