실험 절차

Compound 102 (0.23 g, 7.9 mmol) in a solution consisting of Tol/EtOH/2M Na2CO3 aq (15 mL/2 mL/15 mL) was treated with 4-benzloxy phenylboronic acid (0.12 g, 1.0 mmol) and cat Pd(PPh3)4 and heated to reflux until TLC analysis indicated complete reaction. The reaction mixture was treated with 2 N HCl aq and extracted with EtOAc. The EtOAc layer was washed with saturated NaHCO3 aq, brine and dried over MgSO4. After filtration, the residue was chromatographed on silica gel (1:4 EtOAc/hexanes) to yield the desired product as an orange solid. The orange solid thus obtained was triturated with CH2Cl2 to yield the pdt (2.4 g) as a white solid: Mp=186-187° C.; 1H NMR (DMSO-d6) δ 9.90 (br s, 1 H), 9.05 (br s, 1 H), 7.65 (d, 1 H, J=8.5 Hz), 7.51-7.31 (m, 5 H), 7.19 (d, 1 H, J=8.5 Hz), 7.17 (d, 2 H, J=8.6 Hz), 7.02 (d, 2 H, J=8.7 Hz), 6.86 (dd, 1 H, J=8.5 Hz, 2.4 Hz), 6.70 (d, 2 H, J=1.8 Hz), 6.63 (dd, 1 H, J=8.7 Hz, 2.4 Hz), 5.86 (s, 1 H), 5.14 (s, 2 H); MS 407 (M−H)−.
