A procedure similar to that described in Preparation 10, below, was followed, but using 520 mg of 2-amino-1-(2-naphthyl)ethanol [prepared as described in Preparation 8], 650 mg of 5-[4-(2-oxopropoxy)benzyl]thiazolidine-2,4-dione [prepared as described in Preparation 9], 150 ml of benzene, 100 ml of absolute methanol and 1.25 g of sodium borohydride, to give the title compound in crude form. This crude product was then purified by column chromatography through silica gel, using a 5:1 by volume mixture of ethyl acetate and ethanol as the eluent, to give 490 mg of the title compound melting at between 115° C. and 145° C.
