実験手順
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 10,13-octadecadienoyl chloride instead of isovaleryl chloride, there is obtained 3-hydroxy-4-(10,13-octadec a dienoyloxy)phenyl isopropylaminomethyl ketone; and by interaction of this base with methanesulfonic acid there is obtained the methanesulfonate salt. When this methanesulfonate is reduced with sodium borohydride, using a procedure similar to that described above in Example 30C, there is obtained 3-hydroxy-4-(10,13-octadecadienoyloxy)-alpha-(isopropylaminomethyl)benzyl alcohol methanesulfonate. By catalytic hydrogenation of 3-hydroxy-4-(10,13-octadienoyloxy)phenyl isopropylaminomethyl ketone methanesulfonate, using a procedure similar to that described above in Example 30B, there is obtained 3-hydroxy-4-(octadecanoyloxy)-alpha-(isopropylaminomethyl)benzyl methanesulfonate.
