Procedure

Cyclohexyl alcohol (6 g), 4-hydroxyphenylacetic acid (7.6 g), p-toluenesulfonic acid (1 g) and benzene (300 mL) were refluxed with continuous water separation for 8 hours. The mixture was cooled and washed with a 10% Na2CO3 solution, then with water. Drying over MgSO4 and evaporation of the solvent in vacuo gave 12.24 g of cyclohexyl 4-hydroxyphenylacetate. That compound can be represented by the formula: ##STR25##
