PROBLEM TO BE SOLVED: To provide a simple and inexpensive method for preparing a 2-naphthol derivative without using a fluorination agent which previously required a long reaction step in its preparation and the use of the expensive fluorination agent multi-times. SOLUTION: The method for preparing a 2-naphthol derivative represented by formula (2) comprises reacting a phenylacetic acid halide derivative represented by formula (1) with acetylene in the present of a Lewis acid. Specifically, for example, the reaction of formula (3) can be illustrated. The 2-naphthol derivative is useful as a production intermediate of fluorine substituted naphthalene derivatives useful as liquid crystal materials. COPYRIGHT: (C)2005,JPO&NCIPI
