Versuchsvorschrift
A mixture of 21.8 g of 2-(p-prenylphenyl)propionic acid, 10.2 g of tetrahydrofurfuryl alcohol and 0.4 g of graphite bisulfate in 100 ml of cyclohexane was stirred at room temperature for 8 hours. The mixture was passed through a column of silica gel, and the solvent was evaporated to give 24.5 g of tetrahydrofurfuryl 2-(p-prenylphenyl)propionate. b.p. 135° C./0.08 mmHg, IR νmaxneat ; 1730 cm-1.
