According to the same manner as that described in Example 23, 2-[3-(4-isopropoxyphenyl)propyl]-1,3-dioxolane was condensed with 2,4-thiazolidinedione, and the resulting compound was subjected to catalytic hydrogenation to give crystals of 5-[4-(4-isopropoxyphenyl)butyl]-2,4-thiazolidinedione (yield: 68%). This product was recrystallized from ether-hexane. Colorless prisms, mp: 72-73° C.
