実験手順

A mixture of (S)-1-(4-methoxy-benzyl)-4-(3-trifluoromethyl-phenyl)-imidazolidin-2-one (1.7 g, 4.86 mmol), 4-(4-clorophenoxy)-iodobenzene, (1.77 g, 5.35 mmol), CuI (93 mg, 0.49 mmol), trans-N,N′-dimethyl-cyclohexane-1,2-diamine (119 mg, 0.97 mmol) and K3PO4 (2.06 g, 9.72 mmol) in DMF (17 mL) is degassed and heated to 110° C. under N2 for 16 h. After cooling down to room temperature, the mixture was poured into water (200 mL) and extracted with EtOAc (3×50 mL). The combined organic layer is washed with brine and dried (MgSO4). After removing the drying agent, the solution is concentrated and purified by flash column chromatography (silica gel, EtOAc/hexane 0%˜80%) to provide the desired product (S)-3-[4-(4-chloro-phenoxy)-phenyl]-1-(4-methoxy-benzyl)-4-(3-trifluoromethyl-phenyl)-imidazolidin-2-one (example 154) as a white solid (2.1 g, 78%). 1H NMR (CDCl3, 400 MHz) δ 7.51 (m, 2H), 7.44 (m, 2H), 7.34 (d, 2H), 7.23 (m, 4H), 6.87 (m, 6H), 5.17 (dd, 1H), 4.53 (d, 1H), 4.37 (d, 1H), 3.79 (s, 3H), 3.76 (t, 1H), 3.07 (dd, 1H); HPLC-MS calculated for C30H24ClF3N2O3 (M+H+) 553.1, found 553.1.
