Procedure
15 g (0.5 mole) of an 80% suspension of sodium hydride in mineral oil were introduced, while stirring, into a solution of 37.5 g (0.6 mole) of imidazole in 250 ml of absolute 1,2-dimethyoxyethane. The whole was heated for 30 minutes to the boil and then a solution of 109.6 g (0.4 mole) of 1,3-dichloro-4-phenylisoquinoline in 100 ml of absolute 1,2-dimethoxyethane was added dropwise. The mixture was then boiled for 3 hours under reflux, the solvent was distilled off under reduced pressure and the residue was dissolved in a mixture of methylene chloride and water. The organic phase was washed with water, the sol-was removed under reduced pressure and the product was recrystallized from toluene. M.p. 165° to 168°.
