実験手順

To a solution of 2-{2-[6-allyl-7-chloro-3-(3,5-dimethylphenyl)-2-oxo-1,2-dihydroquinolin-4-yloxy]-ethyl}-piperidine-1-carboxylic acid tert-butyl ester (Example 4, Step 4E: 400 mg in 7.0 mL of dry tetrahydrofuran) at 0° C. was added 2.18 mL of a 1M solution of borane in tetrahydrofuran dropwise over 10 minutes. After 3 hours, the reaction was treated sequentially with sodium hydroxide (0.84 mL of a 3M solution) and hydrogen peroxide (0.29 mL of a 30% solution) and the mixture allowed to warm to room temperature. After 2 hours the mixture was extracted with ethyl acetate, washed with brine and dried over sodium sulfate. Purification of the concentrate by flash chromatography on silica gel (hexane:ethyl acetate, 8:2; then 7:3; then 3:2; then 1:1) gave the title compound (253 mg).
