Procedure
A procedure similar to that described in Preparation 46 was repeated, except that 4.00 g of 3-dimethylaminophenol, 4.5 ml of epibromohydrin, 1.53 g of sodium hydride (as a 55% by weight dispersion in mineral oil) and 50 ml of dimethylformamide were used. The resulting crude product was purified by silica gel column chromatography, using a 1:4 by volume mixture of ethyl acetate and hexane as the eluent, to give 4.18 g of the title compound having an Rf value of 0.36 (on silica gel thin layer chromatography, using a 1:4 by volume mixture of ethyl acetate and hexane as the developing solvent).
