Summary:PURPOSE:To advantageously obtain the subject compound which is an intermediate for agricultural and horticultural insecticides without requiring a phase- transfer catalyst by reacting 4-phenoxyphenol with propylene oxide as raw materials in the presence of a base using water, an alcohol, etc., as a solvent. CONSTITUTION:4-Phenoxyphenol is reacted with propylene oxide in an amount of preferably 0.1-10mol, especially 0.5-3mol based on 1mol 4-phenoxyphenol in the presence of a base, such as sodium hydroxide or pyridine, in a solvent selected from water, alcohols and mixtures of water with alcohols at 0-200 deg.C, preferably at 20-70 deg.C preferably under ordinary pressure to afford the objective compound. Furthermore, although the compound expressed by formula I is mainly obtained, a compound expressed by formula II which is an isomer thereof is simultaneously obtained. As a result, crystallization treatment is carried out to afford the compound expressed by formula I.
