Reaction Steps
9.6 g of 7,7,8,9,9-pentamethyl-1,3,8-triazaspiro[4.5]decane-2,4-dione, 5.2 g of bis(2,3-epoxypropyl)adipate and 0.1 g of potassium hydroxide were reacted in 80 ml of t-butanol, following substantially the same procedure as in Example 1. The desired Compound No. 126 was obtained in the form of white crystals, melting at 180°-184° C.
