Acetic Acid → 5-{4-(1-Methylimidazo[4,5-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 4.1 g of 5-{4-(1-methyl-1H-imidazo[4,5-b]pyridin-2-ylmethoxy)benzyl}-3-triphenylmethylthiazolidine-2,4-dione (prepared as described in Preparation 31) and 160 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 1.45 g of the title compound, melting at 231-232° C.
