Reaction Steps

As pointed out above, a preferred embodiment of this invention employs a mixture of all four optica isomers of the compound of Example 7. This racemic mixture can be prepared by the method described above by reaction of dl-4-(benzoyloxy)mandelic acid with dl-1-methyl-3-(4-benzyloxyphenyl)propylamine in the presence of DCC to give racemic 1-(4-benzyloxyphenyl)-2-oxo-2-[1-methyl-3-(4-benzyloxyphenyl)propylamino]ethanol. Reduction of the latter compound and subsequent removal of the benzyl groups provides racemic 1-(4-hydroxy-phenyl)-2-[1-methyl-3-(4-hydroxyphenyl)propylamino]-ethanol. This compound is more preferably prepared by the following procedure.
