Reaction Steps
Then, one mol of the butadiene derivative and one mol of a benzophenone derivative (compound of the following formula (X)) are condensated under the presence of a dehydrating agent such as anhydrous acetic acid, polyphosphoric acid or sulfuric acid to obtain a phthalide compound represented by the general formula (I) as substantially colorless crystals. ##STR10##
