Versuchsvorschrift
Bromocyclopentane (14 mmol) and 2-nitroimidazole (10 mmol) were used to prepare 1-cyclopentyl-2-nitro-1H-imidazole following the alkylation procedure described for Example 181. The product, thus obtained was reduced under hydrogenation conditions as described in general procedure F to afford 1-cyclopentyl-2-amino-1H-imidazole. This aminoimidazole derivative was converted to 1-cyclopentyl-2-isothiocyanato-1H-imidazole following the general procedure A.
