실험 절차

As described in European Patent No. 48301, 250 g of ethyl 7-chloro-2-oxoheptanoate and 141 g of (S)-2,2-dimethyl cyclopropanecarboxamid were reacted and concentrated. In result, 372.4 g of ethyl (Z)-7-chloro-((S)-2,2-dimethylcyclopropanecarboxamido)-2-hepnoate (2) containing, by gas chromatography assay, 10.5% of ethyl (E)-7-chloro-((S)-2,2-dimethylcyclopropanecarboxamido)-2-heptenoate (3) was obtained.
