실험 절차

To a solution of 6-allyl-7-chloro-3-(3,5-dimethylphenyl)-4-hydroxy-1H-quinolin-2-one (960 mg in 30 mL of tetrahydrofuran) at 0° C. was added 615 mg of 2-(2-hydroxyethyl)-piperidine-1-carboxylic acid tert-butyl ester and 1.04 g of triphenylphosphine followed by 0.56 mL of diethyl azodicarboxylate and the mixture warmed to room temperature. After 20 hours, the solvents were removed in vacuo and the residue purified by flash chromatography on silica gel (hexane:ethylacetate, 85:15; then 80:20; then 90:10) to give the title compound (1.19 g).
