실험 절차

To a solution of 4-[5-(3-chlorophenylamino)-[1,3,4]oxadiazol-2-yl]-benzene-1,2-diamine (210 mg, 0.7 mmol) and 3-(4-formyl-3,5-dimethylphenyl)-propionic acid methyl ester (169 mg, 0.77 mmol) (from step D) in DMSO (2.5 mL) was added Yb(OTf)3 (86 mg, 0.14 mmol) and the mixture was stirred at RT for 72 h. The mixture was poured into water and the resulting precipitate was filtered and washed with water. The solid was purified by flash chromatography using 10% MeOH/CH2Cl2 as eluent to give the title compound as a tan solid. MS: m/z 502.0 (M+1). H1-NMR (DMSO-d6): δ ppm 12.91 (m, 0.6H), 10.93 (s, 0.3 H), 10.48 (dd, 0.3H), 8.33 (s, 0.4H), 8.13 (s, 0.6H), 7.89-7.73 (M, 2.3H), 7.68 (d, 0.3 H), 7.59 (d, 0.4H), 7.52 (m, 1 H), 7.46-7.35 (m, 1H), 7.08 (s, 3H), 3.61 (s, 3H), 2.87 (t, 2H), 2.69 (t, 2H), 2.10 (s, 3H), 2.09 (s, 3H).
