Reaction Steps

Following a procedure similar to that described in Example 30A above, when 3-hydroxy-4-(pivalyloxy)phenyl tert-butylaminomethyl ketone is interacted with one equivalent of sodium methoxide and the resulting sodium phenolate salt is reacted with 3,4,5-trimethoxybenzoyl chloride there is obtained 3-(3,4,5-trimethoxybenzoyloxy)-4-(pivalyloxy)phenyl tert-butylaminomethyl ketone which reacts with hydrochloric acid to yield the hydrochloride salt. When this hydrochloride is catalytically hydrogenated, using the procedure described above in Example 30B, there is obtained 3-(3,4,5-trimethoxybenzoyloxy)-4-(pivalyloxy)-alpha-(tert-butylaminomethyl)benzyl alcohol hydrochloride.
