실험 절차

To (E)-3-(2-{3-[2-(Phenylmethoxy)phenyl]phenyl}phenyl)prop-2-enoic acid (210 mg, 0.52 mmol) of Example 2 (step 2), 2-thiophenesulfonylamide (121 mg, 0.74 mmol) and DMAP (250 mg, 2.04 mmol) in CH2Cl2 (3 mL) was added EDCI (142 mg, 0.74 mmol). After stirring at r.t. for 2 days, the reaction mixture was poured into 1N HCl (or aqueous AcOH) and extracted with EtOAc. The organic layer was washed with brine, dried (MgSO4), filtered and concentrated. Purification by flash chromatography (Tol:EtOAc:AcOH, 1:0:0 to 20:1:0.1) and recrystallization (Hex:CH2Cl2) provided the desired material as a white solid (161 mg, 56%). 1H NMR (acetone-d6) δ 5.13 (2H, s), 6.72 (1H, d), 7.04 (1H, td), 7.1-7.2 (2H, m), 7.2-7.4 (8H, m), 7.4-7.5 (4H, m), 7.55 (1H, t), 7.62 (1H, dt), 7.7-7.8 (3H, m) and 7.92 (1H, dd).
