Reaction Steps

To 70 ml of dimethylformamide were added 8 g of the potassium salt of 7,9-diethyl-6,7,9-trimethyl-1,3,8-triazaspiro[4.5]decane-2,4-dione (Compound 1) and 5.2 g of octyl bromide; the mixture was heated, with stirring, at 60° C for 2 hours. The reaction mixture was then concentrated by evaporation under reduced pressure, and benzene was added to the residue. The resulting benzene solution was washed with water and then dried over magnesium sulphate. After removing the benzene, the resulting oily product was first purified by column chromatography on silica gel (eluent: benzene containing 5% of triethylamine) and then by recrystallization from hexane, giving 3.0 g of Compound 5, mp 65° - 67° C.
