실험 절차

3.1 ml of trifluoroacetic acid were added to a solution of 2.50 g of 5-[4-(1-methylindolin-2-yl-methoxy)benzyl]-3-triphenylmethylthiazolidine-2,4-dione (prepared as described in Preparation 7) in 25 ml of methylene chloride, and the resulting mixture was stirred at room temperature for 1 hour. At the end of this time, the reaction mixture was worked up following the procedure described in Example 1, to give 1.20 g of the title compound, melting at 46.1°-48.9° C.
