[O:1]1[CH2:6][CH2:5][N:4]([C:7]2[CH:12]=[CH:11][C:10]([N+:13]([O-])=O)=[CH:9][C:8]=2[OH:16])[CH2:3][CH2:2]1>[Pd].C(O)C.[H][H]>[NH2:13][C:10]1[CH:11]=[CH:12][C:7]([N:4]2[CH2:3][CH2:2][O:1][CH2:6][CH2:5]2)=[C:8]([OH:16])[CH:9]=110% Palladium on carbon (10 mg, 0.892 mmol) was added to 2-morpholino-5-nitrophenol (prepared as described herein above; 200 mg, 0.892 mmol) in ethanol (20 mL), hydrogen gas was added (40 psi), and the reaction allowed to proceed for 12 h at room temperature. The reaction was monitored by TLC. After completion of the reaction, the reaction mixture filtered through Celite®, and the solvent removed in vacuo. The residue was purified by flash column chromatography (2% CH3OH/CH2Cl2) to provide the title compound 5-amino-2-morpholinophenol (200 mg, 0.937 mmol, 105% yield) as a solid.
