Procedure
Operating as in Example 14, 15.5 g of 4-cyclohexyl-4,5,6,7-tetrahydro-imidazo-[4,5-c]-pyridine, m.p. 150°, are obtained from 18.4 g of histamine dihydrochloride and 24.4 ml of hexahydrobenzaldehyde. A solution of 2.05 g of 4-cyclohexyl-4,5,6,7-tetrahydro-imidazo-[4,5-c]-pyridine and 1.1 g of methyl isothiocyanate in 30 ml of acetonitrile is refluxed for 5 h. The solution is cooled and filtered, and 2.50 g of the title compound, m.p. 232°, are collected.
