Participants

Reaction Steps

A solution of 3.69 g of 4,5,6,7-tetrahydro-imidazo-[4,5-c]-pyridine and 7.47 g of cyclopropyl isocyanate in 20 ml of dry dioxane is refluxed for 1.5 h. After evaporation to dryness, the residue is dissolved in 44 ml of methanol and treated with 11 ml of 2N sodium hydroxide for 1.5 h at room temperature. After neutralization, the solution is extracted with chloroform. Evaporation of the solvent leaves a residue that is taken up in acetonitrile to give 2.12 g of the title compound, m.p. 215°.
