Ammonia → Benzenamine, 4-(4-morpholinyl)-

Participants

Reaction Steps

4-(4-Nitrophenyl)morpholine (10.3 g, 49.5 mmol;) (Lancaster Synthesis) was suspended in methanol (130 ml) and 2 M ammonia in methanol (70 mL) and 5% palladium on carbon (100 mg) was added. The mixture was hydrogenated on a Paar apparatus (50 psi) for 1 h. The reaction was allowed to cool, the catalyst was filtered and the solution was concentrated in vacuo. The crude solid was recrystallized from ethyl acetate/hexane to give 4-(4-morpholinyl)Aniline as a light purple solid (6.2 g, 70% yield, mp 132-133° C.). GC/MS (EI, M+) m/z=178.
