Versuchsvorschrift
To a solution of 2-[4-(1-hydroxy-1-cyclohexyl)-2-methylphenyl]-4,4-dimethyl-2-oxazoline (4.29 g) in acetic acid (40 ml) is added a 10% hydrochloric acid (20 ml), and the mixture is refluxed for two days. The precipitated crystals are collected by filtration, washed with water, and dried to give 4-cyclohexenyl-2-methylbenzoic acid (2.61 g) as white powder.
