Procedure

To a solution of ethyl 4-hydroxycyclohexanoate (8.61 g, 50 mmole) in 50 ml ethanol was added a solution of potassium hydroxide 85% (3.63 g, 55 mmole) and the mixture was stirred for 6 hours at 70° C. The mixture was evaporated under reduced pressure, coevaporated two times with N,N-dimethylformamide and reduced to about 100 ml. 4-Methoxybenzyl chloride (9.4 g, 60 mmole) was added and the mixture was stirred for 18 hours at 60° C. The mixture was evaporated under reduced pressure and 250 ml ethyl acetate was added. The organic phase was washed five times with water, dried with sodium sulfate and evaporated under reduced pressure. Yield: 13.2 g=100% (crude)
