実験手順
Piperidine (2 ml; 20.26 mmol) was added to a solution of 5-chloromethyl-8-hydroxyquinoline (1.87 g; 8.13 mmol) in CHCl3 (50 ml) at 5° C. The mixture was stirred for two days at room temperature. Then the mixture was evaporated under vacuum to dryness. The residue was dissolved in CHCl3, washed with 5% NaHCO3 (2×50 ml), followed by brine (50 ml), dried over Na2SO4 and evaporated to dryness. The residue was crystallized from hexane to give 1.0 g of the title product (50%). M.p. 96° C. TLC (CHCl3; MeOH; NH3=8:2:0.5). Rf=0.63.
