Reaction Steps

10.0 g of 7,7,8,9,9-pentamethyl-1,3,8-triazaspiro[4.5]decane-2,4-dione, 3.0 g of ethylene glycol bis(2,3-epoxypropyl)ether and 0.1 g of potassium hydroxide were reacted in 60 ml of methanol, following substantially the same procedure as in Example 1. The desired Compound No. 166 was obtained in the form of white crystals, melting at 213°-215° C.
