Versuchsvorschrift

A 500 mL roundbottom flask equipped with stir bar and 3-way stopcock charged with MeOH/tetrahydrofuran/water (200 mL of 2:1:1) was purged thoroughly with nitrogen. To this was added 1.0 g of 10% Pd/C followed by addition of 10 g (48.0 mmol) of 3-morpholinyl nitrobenzene. The mixture then was stirred under a hydrogen atmosphere for 4 days (1 atm). The reaction was filtered over GF/F filter paper and the filtrate concentrated in vacuo to remove MeOH and THF. The resulting solid was recovered by filtration, washed with water, air dried, then dried in vacuo to give 7.3 g (83% yield) of the desired aniline as beige crystals.
