Reaction Steps

To a solution of 3-bromo-4-methoxybenzonitrile (1 g, 4.72 mmol) in 10 mL of ethane-1,2-diamine was added sulfur (0.121 g, 3.77 mmol) and the mixture was heated at 110° C. overnight. The mixture was cooled, quenched with water and extracted with ethyl acetate. The organic layer was washed with water and brine (25 mL each), dried over sodium sulfate, filtered, and concentrated to afford the title compound. LCMS: 257 (M+2)+.
