    摘要: A method for the preparation of 5-benzyloxy-2-(4-benzyloxyphenyl)-3-methyl-1H-indole of formula (1) by reaction of 2-bromo-4′-benzyloxypropiophenone and 4-benzyloxyaniline hydrochloride, in which high purity of the product is achieved by isolation of the intermediate, N-(4-benzyloxyphenyl)-α-amino-4-benzyloxypropiophenone of formula (10), in the solid state. The method may be used for the preparation of bazedoxifen of formula (2).
