1-(2-Hydroxyphenyl)-3-(1H-indol-4-yl)prop-2-en-1-one → 1-(2-Hydroxyphenyl)-3-(1H-indol-4-yl)propan-1-one

Participants

Reaction Steps

A mixture of 200 mg of the product of Step A in 10 ml of methanol was hydrogenated in the presence of palladized activated charcoal at room temperature until absorption ceased and was then filtered. The filtrate was evaporated to dryness and the residue was chromatographed over silica. Elution with a 6-3-1 cyclohexane-dichloromethane-triethylamine mixture yielded 143 mg of 1-(2-hydroxyphenyl)-3-(1H-indol-4-yl)-1-propanone melting at ≃143° C.
