The present invention provides an industrial method for preparing aminoalcohol derivatives (I) having a biphenyl group, biphenyloxyacetaldehyde derivatives which are used therefore, preparing methods thereof, and intermediates used for the preparing method.
The present invention also provides a preparing method including processes for preparing a 3-substituted biphenylcarboxylic acid derivative represented by the following general formula:
by allowing a 3-fluorobiphenylcarboxylic acid derivative prepared from a 3-fluorobiphenylcarbonitrile derivative which can be prepared by allowing a 4-halophenol derivative to react with a 2-fluorobenzonitrile derivative which is substituted by a leaving group at 4-position to react with an organometallic reagent.
