Abstract

PURPOSE:To readily obtain the titled substance useful as a synthetic intermediate for antiphlogistics or other medicine from an inexpensive raw material in high yield, by reacting 2-carboxydibenozylmethanes with a strongly acidic ion exchange resin so as to subject the above-mentioned compound to dehydration reaction. CONSTITUTION:A compound expressed by formula I (R is H, halogen alkyl, alkenyl or alkoxy; n is 1-5) is reacted with a strongly acidic ion exchange resin in an inert solvent at 50-120 deg.C to provide the compound expressed by formula II. The strongly acidic ion exchange resin includes preferably polystyrene based ion exchange resin (e.g. Amberlist 15 or Diaion) and may be used in either one of gel type or porous type. The ion exchange resin is used at an amount of 10-300wt.% based on the compound expressed by formula I.
