実験手順

A mixture of 15 parts of 1-(4-fluoro-2-nitrobenzoyl)-aziridine, 12 parts of 1-phenyl-1,3,8-triazaspiro[4,5]decan-4-one, 8.8 parts of methanol and 56 parts of benzene is stirred first for 1.50 hours at reflux and further overnight at room temperature. The reaction mixture is evaporated. The residue is dissolved in trichloromethane and the solution is washed with water. Then there are added 8 parts of methanol and silica gel and the whole is stirred for 10 minutes. The silica gel is filtered off and the filtrate is evaporated. The residue is stirred in 2,2'-oxybispropane. The product is filtered off and crystallized from 4-methyl-2-pentanone. It is filtered off and dried, yielding 13 parts of 4-fluoro-2-nitro-N-[2-(4-oxo-1-phenyl-1,3,8-triazaspiro-[4,5]dec-8-yl)ethyl]benzamide; mp. 160° C.
