Reaction Steps

A solution of 2-(p-methoxybenzoyl)-3-methyl-4-allyl-5-hydroxybenzofuran (3 gm, 9.3 mmoles) in ethanol (150 mL) was hydrogenated in a Parr hydrogenator in the presence of 10% palladium on charcoal at 40 psi for a period of 3 hours. The catalyst was filtered off, washed with some ethanol, and the filtrate was concentrated in vacuo. The residue was recrystallized from hexane to yield (1.1 gm, 38%) of 2-(p-methoxybenzyl)-3-methyl-4-propyl-5-hydroxybenzofuran, mp. 91°-93° C.
