Reaction Steps

To a solution of 9-benzenesulfonyl-6-bromo-3-chloro-9H-pyrido[2,3-b]indole (250 mg, 0.59 mmol, 1 equiv.) in anhydrous dioxane (25 ml) under Argon, Pd(PPh3)4 (102 mg, 0.09 mmol, 0.15 equiv.), K2CO3 (244 mg, 1.77 mmol, 3 equiv.), (E)-2′-(4-methoxyphenyl)ethenylboronic acid (110 mg, 0.77 mmol, 1.3 equiv.) and H2O (5 ml) are added respectively. The mixture is stirred at 100° C. overnight and then filtered over celite which is washed with AcOEt (20 ml) and THF (10 ml). The filtrate is concentrated under reduced pressure and the crude residue is purified over silica gel column (eluant CH2Cl2/PE 7:3). The product is obtained as a white solid (212 mg, 0.40 mmol) in 68% yield.
