Reaction Steps
2-cyclopentyl-1-[p-(N,N-dimethyl-2-aminoethoxy)phenyl]-1-(p-hydroxyphenyl)-1-butanol, which was prepared from α-cyclopentyl-p-hydroxybutyrophenone and p-(N,N-dimethyl-2-aminoethoxy) bromobenzene according to the procedure of example 3, was dehydrated in ethanol in the presence of hydrochloric acid. The product was recrystallized from n-hexane, mp. 112°-120° C. and was found to be an 1:1 mixture of E- and Z-isomers.
