Abstract
PURPOSE: To obtain the titled substance useful as a raw material for a variety of organic syntheses, agricultural chemicals, etc., in high purity and yield, by the reaction of a specific amount of substituted dihydroxybenzene with an organic halide in the presence of a base with a small amount of a diphenoxy derivative formed as a by-product.
CONSTITUTION: A compound expressed by formula I (R is H, halogen or lower alkyl) in an amount of at least 1.3 times (especially 1.8 times) that of the stoichiometric one is reacted with a compound expressed by the formula Ar-X [Ar is group expressed by formula II, III or IV (X1 is H, halogen, CF3, CN or NO2; X2 is H, halogen, CN or NO2), etc.; X is halogen] in the presence of a base, preferably an alkali (earth) metal, hydroxide or carbonate thereof, preferably in a polar solvent and in the presence of a Cu catalyst, at 140W160°C, usually for 3W10hr, to give a compound expressed by formula V.
