Versuchsvorschrift

To a solution of N,N-dimethyl-4-nitro benzamide (23 g, 0.1185 mol) in MeOH (200 mL) was added Pd/C 10% (2.3 g) in portions and the Parr reaction vessel was purged with nitrogen for 10 min. The reaction vessel was fixed in Parr shaker at 60 psi pressure for 3 h. The reaction mixture was filtered through the Celite® pad and the filtrate was concentrated under reduced pressure to afford the title compound [18.0 g, 93%]; LC-MS (ESI): Calculated mass: 164.1; Observed mass: 165.2 [M+H]+ (RT: 0.17 min).
