反応手順

(Step 1) A mixture of 2-fluoro-5-methoxybenzonitrile (10 g) and sodium methanethiolate (5.1 g) was stirred in N,N-dimethylformamide (20 ml) at 60° C. for 3 hr. The reaction solution was treated with water, and extracted with ethyl acetate. The extract was washed successively with 1N hydrochloric acid, aqueous sodium hydrogen carbonate solution and saturated brine, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure. The obtained residue was crystallized from ethyl acetate-hexane to give 5-methoxy-2-(methylsulfanyl)benzonitrile (8.3 g).
