Ammonium formate → (5-Amino-2-morpholinophenyl)methanol

Participants

Reaction Steps

[2-(Morpholin-4-yl)-5-nitrophenyl]methanol (1.38 g, 5.80 mmol) was hydrogenated using ammonium formate (3.67 g, 58 mmol) and Pd/C (10% Pd, 0.62 g, 0.58 mmol) in 50 mL of EtOH. The mixture was stirred for 1 h at room temperature and then filtered through a celite pad. The filtrate was evaporated and the residue was dissolved in DCM and washed with a saturated aqueous solution of Na2CO3. The aqueous layer was extracted with DCM. The combined organic layers were dried over MgSO4, filtered and evaporated to yield expected compound as a brown powder (1.21 g, 99% yield). LC-MS: m/z (ESI) 209.2 [M+H]+. 1H NMR (300 MHz, MeOH-d4) δ7.02; (d, J=15.0 Hz, 1H), 6.83; (d, J=9.0 Hz, 1H), 6.68; (dd, J=6.0 Hz, 1H), 4.71; (s, 2H), 3.82; (t, J=4.5 Hz, 4H), 2.87; (t, J=4.7 Hz, 4H).
