PROCEDURE

实验过程

A racemate (48.4 g) of (2,2-difluorocyclopropyl)methyl 4-nitrobenzenesulfonate was resolved by HPLC (column: CHIRALPAK AD (trade name), 50 mmID×500 mL, DAICEL CHEMICAL INDUSTRIES, LTD., mobile phase:hexane/ethanol=50:50) to give the title compound having a shorter retention time (18.4 g). The steric configuration was determined by X ray structure analysis.
