実験手順
A solution of methyl 4-(3-allyloxyphenoxy)benzoate in N,N-dimethylaniline was heated at 190° C. for 19 hours, cooled, diluted with ethyl acetate, washed with aqueous hydrochloric acid, dried, and evaporated in vacuo. The residue was chromatographed on silica gel eluting with hexane/ethyl ether to give a 40:60 mixture of the title compounds as an oil in 92% yield. NMR.
