Isovaleryl chloride → 3-(Isovaleryloxy)-4-(p-toluyloxy)phenyl tert-butylaminomethyl ketone

Participants

Reaction Steps

Following a procedure similar to that described in Example 2A above, when 3-hydroxy-4-(p-toluyloxy)phenyl tert-butylaminomethyl ketone is interacted with one equivalent of sodium methoxide and the resulting sodium phenolate salt is reacted with isovaleryl chloride there is obtained 3-(isovaleryloxy)-4-(p-toluyloxy)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 2B, there is obtained 3-(isovaleryloxy)-4-(p-toluyloxy)-alpha-(tert-butylaminomethyl)-benzyl alcohol hydrochloride.
