Procedure

A procedure similar to that described in Example 12 was repeated, except that 0.9 g of 5-(4-{3-(4-phenyl-benzyl)imidazo[5,4-b]pyridin-2-ylmethoxy}benzyl)-3-triphenylmethylthiazolidine-2,4-dione (prepared as described in Preparation 55) and 36 ml of a 3:1 by volume mixture of acetic acid and water were used, to give the title compound as a crude product. This crude product was purified by column chromatography through silica gel, using a 1:3 by volume mixture of hexane and ethyl acetate as the eluent, to give 450 mg of the title compound, melting at 189°-191° C.
