実験手順
A procedure similar to that described in Example 12 was repeated, except that 1.16 g of 5-{4-(5-chloro-3-methylimidazo[5,4-b]pyridin-2-ylmethoxy)benzyl}-3-triphenylmethylthiazolidine-2,4-dione (prepared as described in Preparation 45) and 16 ml of a 3:1 by volume mixture of acetic acid and water were used, to give the title compound as a crude product. The product was crystallized by trituration with ethyl acetate, to give 0.38 g of the title compound, melting at 222°-223° C.
