This compound can be obtained in three different ways: 1) The condensation of N-ethyl-N-(p-methoxy-alpha-methylphenylethyl)amine (I) with 2-cyclohexyl-2-(3-chloropropyl)-1,3-dioxolane (II) by means of NaI in refluxing butanone gives 2-[3-(N-ethyl)-N-(p-methoxy-alpha-methylphenylethyl)amino]propyl-2-cyclohexyl-1,3-dioxolane (III), which is hydrolyzed with H2SO4 in refluxing acetone. 2) By the Grignard reaction of cyclohexylmagnesium bromide (V) with 4-[N-ethyl-N-(p-methoxy-alpha-methylphenylethyl)amino]butyric acid ethyl ester (IV) in ether. 3) By condensation of 2-[N-ethyl-N-(p-methoxy-alpha-methylphenylethyl)amino]ethyl chloride (VI) with cyclohexoylacetic acid ethyl ester (VII) by means of sodium in hot toluene.
