Versuchsvorschrift

1.27 g of 2-nitro-α-(piperidino)methyl-1-imidazole-ethanol were dissolved in 25 ml of warm ethanol and treated with a small excess of anhydrous ethereal hydrogen chloride. The mixture was then allowed to cool and crystallize for several hours. There were obtained 1.4 g of 2-nitro-α-(piperidino)methyl-1-imidazole-ethanol hydrochloride in the form of a very pale cream colored microcrystalline solid identical with the product prepared as described in Example 3(b).
