실험 절차

3,4-Dichloroaniline (Aldrich) was treated with di-tert-butyl dicarbonate (Aldrich) using conventional procedures to produce the N-BOC aniline. The N-BOC aniline was treated with sodium hydride in THF and then with iso-butyl 2-bromoacetate (from Example AD above) to produce the N-BOC N-(3,4-dichlorophenyl)glycine iso-butyl ester. The BOC group was then removed using General Procedure AN above to afford the title compound. The reaction was monitored by tlc on silica gel (Rf=0.78 in 50% EtOAc/hexanes) and purification was by preparative plate chromatography (silica gel using 50% EtOAc/hexanes as the eluant).
