Versuchsvorschrift

A solution of 2-(4,4-diethylcyclohex-1-enyl)-5-methoxyphenylamine (2.6 g, 10 mmol) prepared in Example (6e) and bis(2-chloroethyl)amine hydrochloride (2.2 g, 12 mmol) in 1,2-dichlorobenzene (10 mL) was stirred at an external temperature of 210° C. Nitrogen gas was blown into the reactor several times during the reaction to remove the excess hydrogen chloride gas in the reactor. After 1 hour, the reaction mixture was cooled to room temperature, and then saturated aqueous sodium hydrogencarbonate was added and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate. The desiccant was filtered off and the filtrate was concentrated under reduced pressure. The resultant residue was purified by NH silica gel column chromatography (ethyl acetate/hexane) to give 1.4 g of the title compound as a yellow oil.
