实验步骤: To a solution of (2-amino-ethyl)-carbamic acid tert-butyl ester (1 eq.) in DCM was added TEA (3 eq.). The reaction was cooled to 0° C. Acetyl chloride (1 eq.) was filtered through a pad of alumina then added dropwise in solution in DCM to the reaction at 0° C. The reaction was stirred at 20° C. for 4 h. The crude was diluted with DCM, washed twice with water, then twice with a saturated aqueous solution of NaHCO3. The organic layer was dried over MgSO4, filtered and concentrated under reduced pressure to afford (2-acetylamino-ethyl)-carbamic acid tert-butyl ester. The compound was used as such without further purification. washed twice with water The organic layer was dried over MgSO4 filtered concentrated under reduced pressure
