Procedure

(see, e.g., Greig, I. R., et al., J Med Chem 2006, 49, 7487-92; Li, X., et al., J Med Chem 2003, 46, 5663-73). To a mixture of 50 (205 mg, 0.49 mmol), Pd(PPh3)4 (27 mg, 0.02 mmol) and (E)-2-phenylvinylboronic acid (112 mg, 0.74 mmol) in 1,4-dioxane: H2O (3 mL/2 mL) was added Na2CO3 (153 mg, 1.45 mmol), followed by stirring at 90° C. overnight. To the reaction mixture was added H2O (10 mL) and the aqueous layer was extracted with EtOAc (10 mL×2). The combined organic layer was washed with brine, dried (Na2SO4), filtered and concentrated under reduced pressure. Crude was subjected to flash column chromatography on silica gel to provide the title compound (216 mg, 90%) as a light yellow oil which solidified upon standing. 1H NMR (500 MHz, CDCl3) δ 7.80 (d, J=16.1 Hz, 1H), 7.74 (s, 1H), 7.63 (d, J=7.6 Hz, 2H), 7.41 (t, J=7.6 Hz, 2H), 7.39-7.33 (m, 3H), 7.30 (t, J=7.7 Hz, 3H), 7.07 (t, J=7.4 Hz, 1H), 6.98 (d, J=8.6 Hz, 2H), 6.95 (d, J=8.3 Hz, 2H), 5.69 (s, 2H), 4.51 (q, J=7.1 Hz, 2H), 2.71 (s, 3H), 1.49 (t, J=7.0 Hz, 3H). 13C NMR (125 MHz, CDCl3) δ 165.76, 157.04, 156.79, 154.93, 152.39, 141.19, 136.28, 134.74, 133.60, 132.13, 129.69, 129.50, 128.81, 127.69, 127.33, 123.28, 118.94, 118.82, 116.48, 110.28, 61.93, 49.80, 16.30, 14.30.
