Acetic Acid → 5-{4-(6-Chloro-3-methylimidazo[5,4-b]pyridin-2-ylmethoxy)benzyl}thiazolidine-2,4-dione

Participants

Reaction Steps

A procedure similar to that described in Example 12 was repeated, except that 1.40 g of 5-{4-(6-chloro-3-methyl-3H-imidazo[4,5-b]pyridin-2-ylmethoxy)benzyl}-3-triphenylmethylthiazolidine-2,4-dione (prepared as described in Preparation 65) and 20 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 0.75 g of the title compound, melting at 203-205° C.
