Versuchsvorschrift

To a solution of 2-methoxyphenethylamine (1.98 g) in diethylether (20 ml) was added dropwise under ice-cooling thiophosgene (1.54 g). The mixture was stirred at room temperature for 1 hour. To the solution was added water (30 ml). The mixture was extracted with diethylether (60 ml), dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give (2-methoxyphenethyl)isothiocyanate (1.80 g, yield: 71%) as brown oil.
