Versuchsvorschrift

In ethanol/ethyl acetate was dissolved 100 mg of (R)-(-)-5-[(1-methyl-3-indolyl)carbonyl]-4,5,6,7-tetrahydrobenzimidazole obtained in Example 43(b), and a solution of hydrogen chloride in ethyl acetate was added thereto. The thus formed crystal was collected and recrystallized from ethanol to obtain 70 mg of (R)-(-)-5-[(1-methylindol-3-yl)carbonyl]-4,5,6,7-tetrahydrobenzimidazole hydrochloride.
