    • A typical experimental procedure for the synthesis of 4a is given as follows: to a test tube equipped with a magnetic stirrer chip were added 1 (0.082 g, 0.25 mmol, 2a (0.267 g, 1.5 mmol, 3 (0.041 g, 0.25 mmol, KHCO3 (0.050 g, 0.50 mmol, DMF (4 mL, and H 2O (1 mL, The mixture was stirred at 100°C for 10 min. Then, a DMF solution of PdCl2(PhCN)2 (0.025 M, 0.20 mL, 0.0050 mmol) was added and the mixture was stirred at 100°C for 24 h. After pouring into brine (10 mL, the aqueous phase was extracted three times with CHCl 3 (5 mL each, After drying over magnesium sulfate, the organic solution was concentrated and was precipitated into a large excess amount of methanol to give 4a in a 76% yield (0.096 g, 1H NMR (300 MHz, CDCl3, δ) 6.19-8.04, C6H5 and -C 6H4- 28H, 13C NMR (75 MHz, CDCl3, δ) 126
