Method for producing an oxetane ring-containing biphenyl compounds

And 3-hydroxymethyl-oxetane compound of the following general formula (1), 4,4'-bis and (chloromethyl) biphenyl, in a reaction solvent, is reacted in the presence of a base, the following general formula (2) an oxetane ring-containing biphenyl compounds, by a single reaction step, easily, and in order to efficiently manufacture, a non-aromatic (such as aliphatic) hydrocarbon used as the reaction solvent, using an alkali metal hydroxide as a base, preferably, the reaction is carried out while removed by azeotrope with the byproduct water reaction solvent.
