摘要: A method is disclosed for the preparation of optically pure isomers of formoterol by the reaction of an optically pure 4-benzyloxy-3-formamidostyrene oxide with an optically pure 4-methoxy-&agr;-methyl-N-(phenylmethyl)benzeneethanamine followed by debenzylation. Useful intermediates in the process are also disclosed, as are the novel L-tartrate salt of R,R-formoterol and pharmaceutical compositions thereof.
