실험 절차

A procedure similar to that described in Example 6 was repeated, except that 500 mg of 5-[4-(3-methylimidazo[5,4-b]pyridin-2-ylmethoxy)benzyl]-3-triphenylmethylthiazolidine-2,4-dione (prepared as described in Preparation 16), 1 g of 10% w/w palladium-on-charcoal and 100 ml of methanol were used, to give 77 mg of the title compound, melting at 223-225° C.
