Procedure
Following a procedure similar to that described in Example 2A above, when 3-hydroxy-4-(nicotinoyloxy)phenyl tert-butylaminomethyl ketone is interacted with one equivalent of sodium methoxide and the resulting sodium phenolate salt is reacted with 9-octadecenoyl chloride there is obtained 3-(9-octadecenoyloxy)-4-(nicotinoyloxy)phenyl tert-butylaminomethyl ketone which reacts with methanesulfonic acid to yield the methanesulfonate salt. When this methanesulfonate is reduced with sodium borohydride using the procedure described above in Example 30C, there is obtained 3-(9-octadecenoyloxy)-4-(nicotinoyloxy)-alpha- (tert-butylaminomethyl)benzyl alcohol methanesulfonate.
