Procedure

A procedure similar to that described in Example 12 was repeated, except that 3.00 g of 5-{4-(6-bromo-3-methylimidazo[5,4-b]pyridin-2-ylmethoxy)benzyl}-3-tri-phenylmethylthiazolidine-2,4-dione (prepared as described in Preparation 60) and 40 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 crystallized by trituration with ethyl acetate, to give 1.75 g of the title compound, melting at 204°-205° C.
