Potassium Hydroxide → 2,2-Bis{4-[2-hydroxy-3-(7,7,9,9-tetramethyl-2,4-dioxo-1,3,8-triazaspiro[4.5]dec-3-yl)propoxy]cyclohexyl}propane

Participants

Reaction Steps

40.0 g of 7,7,9,9-tetramethyl-1,3,8-triazaspiro[4.5]decane-2,4-dione, 17.5 g of 2,2-bis[4-(2,3-epoxypropoxy)cyclohexyl]propane and 2.0 g of potassium hydroxide were reacted in 300 ml of methanol, following substantially the same procedure as was described in Example 1. The desired Compound No. 118 was obtained in the form of a white powder, having an Rf value of 0.56 on thin-layer chromatography on silica gel using a 8:1:1:1 by volume mixture of ethyl acetate, benzene, ethanol and triethylamine as developing solvent.
