A solution of 2.9 g of 4-ethyl-4,5,6,7-tetrahydro-imidazo-[4,5-c]-pyridine (Farmaco, Ed. Sci. 1967, 22, 821) and 3 g of methyl isothiocyanate in 32 ml of acetonitrile and 8 ml of ethanol is refluxed for 8 h. The solution is evaporated in vacuo, and the residue crystallized from diethyl ether to give 3 g of 4-ethyl-5-(N-methyl-thiocarbamoyl)-4,5,6,7-tetrahydro-imidazo-[4,5-c]-pyridine, m.p. 230°.
