26.3 g of 7,7,8,9,9-pentamethyl-1,3,8-triazaspiro[4.5]decane-2,4-dione, 17.0 g of 2,2-bis[p-(2,3-epoxypropoxy)phenyl]propane and 0.5 g of potassium hydroxide were added to 200 ml of methanol, and the mixture was refluxed for 8 hours. After completion of the reaction, the mixture was allowed to cool and the crystals which precipitated were washed with methanol and then recrystallized from benzene to give Compound No. 2 in the form of white crystals melting at 241°-244° C.
