Versuchsvorschrift

A mixture of 4-ethylbenzoic acid (5.12 g), thionyl chloride (3.0 ml) and methanol (150 ml) was heated and refluxed. After 3 hours, the mixture was concentrated under reduced pressure to give methyl 4-ethylbenzoate (5.59 g). this product was used in the subsequent step without purification.
