Reaction Steps

A solution of 44 g (234 mmol) of 2-propyl-1-benzopyran-4-one in 350 ml of ethanol and 125 ml of concentrated hydrochloric acid is hydrogenated for 8 hours under a pressure of 500 kPa, in the presence of 14 g of 10% palladium on carbon containing 50% of water. The mixture is then filtered and the filtrate is concentrated under reduced pressure. By chromatography of the residue on a silica column using dichloromethane, 26 g of product are obtained in oil form.
