Participants

Reaction Steps

To a solution of ethyl 5-{4-[5-(3,4-dichloro-benzoylamino)pyridin-2-yloxy]phenyl}pentanoate (8.79 g, 18.0 mmol) in THF (140 mL) was added sodium borohydride (3.14 g, 144 mmol), and the resulting solution was refluxed for 3 hours under a nitrogen atmosphere. The resulting reaction solution was cooled with ice, and treated with 1 N hydrochloric acid. The resulting solution was extracted with ethyl acetate. The ethyl acetate layer was washed with a saturated sodium bicarbonate solution and brine. The ethyl acetate layer was dried over anhydrous magnesium sulfate, and evaporated. The residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=1:2), to thereby yield 7.07 g of the title compound.
