摘要：
An improved method for the preparation of optically pure isomers of Formoterol is disclosed, particularly the (R,R)-isomer.
A method of preparation of substantially enantiomerically pure (R,R)-1-(4-Benzyloxy-3-nitro-phenyl)-2-[[2-(4-methoxy-phenyl)-1-methyl-ethyl]-(1-phenyl-ethyl)-amino]-ethanol to use in the production of (R,R)-Formoterol is also disclosed
