Procedure
4-(1-benzyl-piperidin-4-yl)-1-(5-isopropyl-2,4-bismethoxymethoxy-benzoyl)thiosemicarbazide (the crude product F66-02 of the previous step) and 5% aqueous sodium hydroxide were placed in a 10 mL eggplant shaped flask and heated under reflux for 3 hours. After completing the reaction, the reaction mixture was extracted with methylene chloride, and the extract was dried over anhydrous sodium sulfate. After filtration and evaporation, the residue thus obtained was subjected to the next reaction without further purification.
