YieldReaction ConditionsOperation in experiment
88% With triethylamine; In dichloromethane; at 20℃; for 96h; To a solution of 4-N-(2-aminoethyl)1-N-Boc-piperazine (2.06 g, 8.99 mmol) in CH2CI2 was added triethylamine (2.5 ml_, 17.9 mmol) and 2,4- dichlorobenzenesulfonyl chloride (2.65 g, 10.8 mmol). The reaction mixture was stirred at room temperature for 4 days. The reaction was then concentrated in vacuo and purified by column chromatography (10-70percent ethyl acetate:hexane) to produce 3.46 g (88percent) of the title compound as a white solid: LCMS (m/z): 438.0/440.0 I(M/M+2)+H].
