反応手順

A mixture of 1-(4-nitrophenyl)-2-propanol (Schadt, F. L.; et al. J. Am. Chem. Soc., 1978, 100, 228., 2.2 g, 12.3 mmol), iron powder (3.3 g, 59.1 mmol), ammonium chloride (370 mg, 6.9 mmol), ethanol (48 mL) and water (24 mL) was heated at reflux temperature for 2 h. The mixture was cooled and filtered through a pad of Celite. The filtrate was concentrated. The residue was diluted with ethyl acetate (200 mL) and washed with water (2×100 mL). The organic layer was dried (MgSO4), and concentrated. Purification by flash column chromatography on silica gel eluting with hexane/ethyl acetate (1:1) to afford 1.45 g (78%) of the title compound as a yellow oil: 1H-NMR (CDCl3) δ 7.00 (2H, d, J=8.6 Hz), 6.64 (2H, d, J=8.8 Hz), 3.99-3.89 (1H, m), 3.60 (2H, br s), 2.72-2.52 (2H, m), 1.22 (3H, d, J=6.2 Hz).
