3,3-dimethylpentanoyl chloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Following a procedure similar to that described above in Example 2A, when 3-hydroxy-4-(isovaleryloxy)phenyl isopropylaminomethyl ketone is interacted with one equivalent of sodium methoxide and the resulting sodium phenolate salt is reacted with 3,3-dimethylpentanoyl chloride there is obtained 3-(3,3-dimethylpentanoyloxy)-4-(isovaleryloxy)phenyl isopropylaminomethyl ketone; and by interaction of this base with hydrochloric acid there is obtained the hydrochloride salt. When this hydrochloride is catalytically hydrogenated, using a procedure similar to that described above in Example 2B, there is obtained 3-(3,3-dimethylpentanoyloxy)-4-(isovaleryloxy)-alpha-(isopropylaminomethyl)benzyl alcohol hydrochloride.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
