Procedure
A procedure similar to that described in Preparation 46 was repeated, except that 8 g of 3-phenyl-1-propanol, 9.64 ml of epibromohydrin, 2.56 g of sodium hydride (as a 55% by weight dispersion in mineral oil) and 100 ml of anhydrous dimethylformamide were used. The resulting crude product was purified by silica gel column chromatography, using a 1:6 by volume mixture of ethyl acetate and hexane as the eluent, to give 7.2 g of the title compound as a colorless oil having an Rf value of 0.36 (on silica gel thin layer chromatography, using a 1:5 by volume mixture of ethyl acetate and hexane as the developing solvent).
