실험 절차

A solution of 4-(4-nitrophenyl)dibenzo[b,d]furan (22 g) in EtOAc (800 mL) was hydrogenated in presence of Pd/C (10%, 4.2 g) for 12 h at rt under 2 Kg of pressure. The reaction mixture was filtered, and the filtrates were concentrated. The residue was crystallized from chloroform/PetEther (6/4) to give the title compound (16 g, 84%) as a white solid. 1H NMR (DMSO-d6, 300 MHz) δ 8.15 (d, 1H, J=7.6 Hz), 7.97 (d, 1H, J=7.6 Hz), 7.72 (d, 1H, J=8.1 Hz), 7.65 (d, 2H, J=8.4 Hz), 7.57 (d, 1H, J=8.6 Hz), 7.50 (m, 1H), 7.38 (m, 2H), 6.72 (d, 2H, J=8.4 Hz), 7.35 (s, 2H). M+(LC/MS(ESI)): 260.2
