Procedimiento

A mixture of 25 g of product from Example 102, 72.3 g of 1-iodoheptane, 61.65 g of potassium carbonate and 500 ml of 2-butanone is heated at reflux temperature for 44 hours. The cooled reaction mixture is filtered and concentrated in vacuo. The oily residue is purified by chromatography (silica gel: 10% ethyl acetate/hexane) to give 53.7 g of the desired product.
