Following a procedure similar to that described in Example 2A above when 3-hydroxy-4-(3,3-dimethylcyclobutanecarbonyloxy)phenyl isopropylaminomethyl ketone is interacted with one equivalent of sodium methoxide and the resulting sodium phenolate salt is reacted with 2,5-hexadienoyl chloride there is obtained 3-(2,5-hexadienoyloxy)-4-(3,3-dimethylcyclobutanecarbonyloxy)phenyl isopropylaminomethyl ketone which reacts with hydrochloric acid to yield the hydrochloride salt. When this hydrochloride is reduced with sodium borohydride, using a procedure similar to that described above in Example 30C, there is obtained 3-(2,5-hexadienoyloxy)-4-(3,3-dimethylcyclobutanecarbonyloxy)-alpha-(isopropylaminomethyl)benzyl alcohol hydrochloride.
