を意味する。After distilling off the ethanol, ethyl ether is added to the residue to extract and remove by-produced 3,5-dimethylpyrazole, and the residue is extracted with boiling ethyl acetate. Insoluble matter was removed, and the ethyl acetate extract was washed with an IM citric acid aqueous solution and water, dried over sodium sulfate, and ethyl acetate was distilled off. The residual solid 1.58r was placed on a silica gel 30f column, and 3,5-dimethyl-1-nitroguanylpyrazole was first flowed out using ethyl acetate as a developing solvent, and then eluted with ethyl acetate-acetone = 2:1 to obtain the residue. 1.33 r of colorless crystals were reprecipitated from hot ethyl acetate-isopropyl ether to give N-[N-(3-trans-ethoxycarbonyloxirane-2-carbonyl).
