Versuchsvorschrift
Following the procedure described above in Example 58A but using 3,4-dihydroxyphenyl isopropylaminomethyl ketone hydrochloride instead of 3,4-dihydroxyphenyl tert-butylaminomethyl ketone hydrochloride and 2,3,4-trimethylbenzoyl chloride instead of isovaleryl chloride, there is obtained 3-hydroxy-4-(2,3,4-trimethylbenzoyloxy)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-hydroxy-4-(2,3,4-trimethylbenzoyloxy)-alpha-(isopropylaminomethyl)benzyl alcohol hydrochloride.
