8.4 g (35 mmol) of the compound (11) and 22.0 g (119 mmol) of methyl 3-cyclohexyl-3-oxo-propionate are heated at 130° C. in a Claisen apparatus for 4 hours under application of a weak vacuum, the methyl alcohol formed being distilled off. The excess methyl 3-cyclohexyl-3-oxo-propionate (boiling point 75°-76° C./0.05 mm Hg) is then distilled off from the mixture. A brownish highly viscous oil of N-phenyl-N'-[1,1-bis-(5-cyclohexyl-3,5-dioxo-2-oxa-pentyl)-6-cyclohexyl-4,6-dioxo-3-oxa-hexyl]-urea (12) remains and can be further used without additional purification.
