    Abstract: PURPOSE: A preparation method of 3-isochromanone by reacting o-tolyacetic acid with sulfuryl chloride and treating obtained 2-chloromethylphenylacetic acid with a base is provided which is useful as an intermediate for manufacturing a germicide. CONSTITUTION: 3-Isochromanone is prepared by reacting o-tolyacetic acid with sulfuryl chloride in the presence of a free radical initiator, e.g. AIBN, followed by ring closure of the 2-chlorometylphenylacetic acid so formed with a base, e.g. potassium bicarbonate. For an example, 750g o-tolyacetic acid and 1323ml fluorobenzene are reacted and mixed under an atmosphere of nitrogen and reacted with 11.3g AIBN and 680.3g sulfuryl chloride at 80°C for 1 hr. The reactant is added with 908g saturated potassium bicarbonate and 3.3g potassium iodide to give 453.7g 3-isochromanone(yield:60.4%).
