The ethyl 2-allyl-2-(3-hydroxyphenyl)butyrate used as a starting material was obtained using the procedures described in the portion of Example 1 which is concerned with the preparation of starting materials except that allyl bromide was used in place of ethyl iodide in the second alkylation step. The intermediate so obtained, ethyl 2-allyl-2-(3-methoxyphenyl)butyrate gave the following characteristic NMR signals: 0.76 (t, 3 H), 1.18 (t, 3 H), 2.05 (m, 2 H), 2.75 (m, 2 H), 3.80 (s, 3 H), 4.15 (q, 2 H), 5.15 (m, 2 H), 5.50 (m, 1 H), 6.80 (m, 3 H), 7.22 (m, 1 H). ##STR2##
