실험 절차

Following transesterification General Procedure AB above and using N-(3,4-dichlorophenyl)alanine methyl ester (from Example A9 above) and cyclopentanol (Aldrich), the title compound was prepared as an oil. The reaction was monitored by silica gel tlc (Rf=0.66 in 25% EtOAc/hexanes). Purification was by preparative plate chromatography (silica gel using 25% EtOAc/hexanes as the eluant).
