実験手順

A mixture of 5-chloromethyl-8-hydroxyquinoline hydrochloride (3.45 g; 15 mmol), imidazole (1.02 g; 15 mmol) and diisopropylethylamine (5.25 ml; 30 mmol) in CHCl3 (60 ml) was stirred for 24 h at room temperature and then for 3 h at 60° C. After cooling, the mixture was evaporated, washed with ethyl acetate (50 ml) and then hexane (50 ml). The residue was crystallized from a mixture of toluene and ethanol (abs.) to give 0.83 g (29%) of title product. M.p. 182° C.
