Reaction Steps

N-methyl-N-(phenylsulfonyl)-2-chloro-6-fluorobenzohydrazonoyl chloride (1.10 g), 4-butyl-2-chlorobenzonitrile (0.60 g) and anhydrous aluminum chloride (0.50 g) are added to o-dichlorobenzene (10 ml) and stirred at 120° C. for 1 hour. On completion of the reaction, chloroform (100 ml) is added and washed with dilute hydrochloric acid. After washing with water, the organic layer is dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The concentrate is purified by silica gel column chromatography using mixed solution of hexane-ethyl acetate as eluent to give 0.70 g of compound (refractive index: 1.5667).
