Reaction Steps
To a solution of 6.0 g of 7,9-diethyl-6,7,9-trimethyl-3-octyl-1,3,8-triazaspiro[4.5]decane-2,4-dione (Compound 5) obtained as described in Example 4, in 40 ml of methanol were added 3 drops of concentrated hydrochloric acid and 3.5 g of ethylene oxide. The mixture was heated at 110° C for 24 hours in a sealed tube and then concentrated to give 6.5 g of Compound 118 as an oil. This product had an Rf value of 0.33 on thin layer chromatography on a 0.25 mm thick layer of silica gel (Kieselgel 60F 254, available from Merck & Co.; eluent, benzene containing 5% of triethylamine).
