Iodoethane → m-(Ethylthio)aniline

Participants

Reaction Steps

Sodium hydride (60% in oil, 2.3 g) was suspended in a mixed solvent of tetrahydrofuran (35 mL) and N,N-dimethylformamide (15 mL), and 3-aminobenzenethiol (5.0 g) was added dropwise at room temperature. The mixture was stirred at the same temperature for 5 min, iodoethane (6.86 g) was added, and the mixture was stirred for 30 min. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=9:1→4:1) to give the title compound as a yellow oil (yield 5.0 g, 82%).
