Versuchsvorschrift
The title compound, brown gum, MS: m/e=530.3 [(M+H, was prepared in accordance with the general method of example 1 and 2 from 2-methoxy-6-methylsulfanyl-N-(2-oxo-cyclopentyl)-4-trifluoromethyl-benzamide (intermediate M) and 2,6-diazaspiro[3.3]heptane-2-carboxylic acid 1,1-dimethylethyl ester ethanedioate (CAS 1041026-71-4). The cis- and trans-isomer could be separated by column chromatography.
