实验步骤: N-bromoacetyl-N′-BOC-ethylenediamine (3) is dissolved in 50% TFA in dichloromethane (5 ml of the solution per mmol of 3) at 20° C. The deprotection is allowed to proceed for 30 min, then the reaction mixture is concentrated on a rotary evaporator and solidifies upon addition of dry ethyl ether. The solid material is filtered off, washed with ether/petroleum ether on filter and dried. The desired N-bromoacetyl-ethylenediamine is obtained in the form of triflouroacetate salt. the reaction mixture is concentrated on a rotary evaporator solidifies upon addition of dry ethyl ether The solid material is filtered off washed with ether/petroleum ether on filter dried
