Acetic Acid → Methyl 2-(4-hydroxyphenyl)propanoate

Participants

Reaction Steps

In a mixture of 12ml of hydroiodic acid, 90ml of acetic acid and 1g of phosphorus 10g of 2-(4-methoxyphenyl)propionic acid was refluxed for 3 hours and the reaction mixture was concentrated. 20ml of methanol and 2ml of sulfuric acid were added to the residue and the mixture was refluxed for one hour. After the methanol was concentrated, the water was added to the residue and extracted with ether. The extract was washed over magnesium sulfate and the ether was distilled off. The residue was distilled under reduced pressure to give the object compound having b.p. 150° - 153° C/6mm Hg in a yield of 6.7g (67%)
