Hydrochloric Acid → 5-Chloro-2-(methylthio)benzonitrile

Participants

Reaction Steps

(Step 1) A mixture of 5-chloro-2-fluorobenzonitrile (5.0 g) and sodium methanethiolate (2.48 g) was stirred in N,N-dimethylformamide (20 ml) at 60° C. for 1 hr. The reaction solution was treated with 1N hydrochloric acid, and extracted with ethyl acetate. The extract was washed with saturated brine, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give 5-chloro-2-(methylsulfanyl)benzonitrile (5.7 g).
