Following a procedure similar to that described in Example 13A above, when 3-hydroxy-4-(isovaleryloxy)phenyl tert-butylaminomethyl ketone is interacted with one equivalent of sodium methoxide and the resulting sodium phenolate salt is reacted with 1,3-dimethylcyclobutanecarbonyl chloride there is obtained 3-(1,3-dimethylcyclobutanecarbonyloxy)-4-(isovaleryloxy)-phenyl tert-butylaminomethyl ketone which reacts with hydrochloric acid to yield the hydrochloric salt. When this hydrochloride is catalytically hydrogenated, using the procedure described above in Example 13B, there is obtained 3-(1,3-dimethylcyclobutanecarbonyloxy)-4-(isovaleryloxy)-alpha-(tert-butylaminomethyl)-benzyl alcohol hydrochloride.
