Versuchsvorschrift

A procedure similar to that described in Preparation 46 was repeated, except that 4 g of 8-phenyloctyl alcohol, 3.18 ml of epibromohydrin, 0.85 g of sodium hydride (as a 55% by weight dispersion in mineral oil) and 80 ml of anhydrous dimethylformamide were used, to give 2.42 g of the title compound having an Rf value of 0.51 (on silica gel thin layer chromatography, using a 1:6 by volume mixture of ethyl acetate and hexane as the developing solvent).
