Versuchsvorschrift

A solution of p-nitrobenzylbromide (5.40 g, 25 mmol) in acetonitrile (60 ml) is added dropwise to a stirred solution of aqueous methylamine (65 mL, 40 wt. %, 0.75 mol) in acetonitrile (50 mL) at 0°. After stirring an additional 15 minutes, the solution is poured into brine and extracted 2× with dichloromethane. The combined organic layers are washed with brine, dried over sodium sulfate, filtered, and concentrated in vacuo to give 4-(methylaminomethyl)nitrobenzene (4.04 g).
