Methanol → 2-Amino-2-(4-fluorophenyl)propane-1,3-diol

Participants

Reaction Steps

A suspension of 2-(4-fluorophenyl)-2-nitroproane-1,3-diol (Method 11; 4.5 g, 20.9 mmol) and Raney nickel (0.45 g, 5.23 mmol) in MeOH (50 ml) was degassed and stirred under H2 (48 psi) for 2 hours. The catalyst was removed by filtration. The filtrate was concentrated and recrystallized from hexane:EtOAc (1:1) to give the title compound (2.35 g, 61%) as a white solid. NMR (400 MHz) □ 7.55 (m, 2H), 7.07 (m, 2H), 4.65 (t, J=5.2 Hz, 2H), 3.49 (m, 4H), 1.76 (s, 2H).
