Procedure

A solution of 17 g (0.042 mole) 1-[4-(2,3-dichlorophenyl)-2-butenyl]-3-heptylimidazolium chloride in 250 ml absolute ethanol and 1.5 g 10% Pd/C catalyst are placed in a small Parr bottle, and hydrogenated at 25 psi for ca. 2 hours. Additional H2 is added as needed to maintain 25 psi pressure. The reaction mixture is filtered and the solvent is evaporated to provide the title compound.
