4-hydroxy-3-methoxy-N-[1-oxo-2-phenylmethylidene-1,2,3,4-tetrahydronaphthalen-7-yl]phenylacetamide → 4-Hydroxy-3-methoxy-n-[1-oxo-2-phenylmethyl-1,2,3,4-tetrahydronaphthalen-7-yl]phenylacetamide

Reaction Steps

The compound of Example 248 (500 mg) is dissolved in ethyl acetate (20 ml), and thereto is added 10% palladium on carbon (50 mg), and the mixture is subjected to catalytic hydrogenation at 25° C. The catalyst is removed by filtration, and the solvent is evaporated under reduced pressure. The residue is purified by silica gel column chromatography (eluent: gradient from 0% to 100% hexane/ethyl acetate) to give the desired compound (350 mg).
