Reaction Steps
A procedure similar to that described in Preparation 46 was repeated, except that 15.0 g of 5-(4-hydroxybenzyl)thiazolidine-2,4-dione, 8.80 g of sodium hydride (as a 55% by weight dispersion in mineral oil), 17 ml of 2-(2-bromoethyl)-1,3-dioxolane and 80 ml of dimethylformamide were used, and that the product was purified by column chromatography through silica gel, using a 1:1 by volume mixture of hexane and ethyl acetate as the eluent, to give 6.67 g of the title compound, melting at 102°-104° C.
