实验步骤: (1-Benzyl-2-hydroxy-3-isobutylamino-propyl)-carbamic acid tert-butyl ester (2) (24.50 g, 72.80 mmol, 1 equiv) and triethylamine (7.37 g, 72.80 mmol, 1 equiv) were dissolved in dichloromethane (500 mL). The solution was cooled to −1.5° C., followed by the dropwise addition of benzylchloroformate (12.40 g, 72.80 mmol, 1 equiv). The solution was stirred at 0° C. for 24 h. Due to the incompleteness of the reaction, benzylchloroformate (2.40 g, 14.07 mmol) and triethylamine (1.44 g, 14.23 mmol) were added to the solution. The solution was stirred at room temperature for 24 h. The solution was diluted with 2% Na2CO3 solution (300 mL) and the mixture was stirred for 10 min. The organic layer was separated, washed with water (2×) and saturated sodium chloride solution (1×). The organic layer was dried on MgSO4, filtered, and evaporated to dryness to obtain the desired product as a yellow colored oil (34.30 g, 72.80 mmol, quantitative). LRMS (ES+): m/z 471 [M+H]+. were added to the solution The solution was stirred at room temperature for 24 h the mixture was stirred for 10 min The organic layer was separated washed with water (2×) and saturated sodium chloride solution (1×) The organic layer was dried on MgSO4 filtered evaporated to dryness
