A solution of Pd(PPh3 )2C12 (0.073 g, 0.12 mmol), 7 (0.19 g, 1.3 mmol), 8 (0.40 g, 1.2 mmol), and triethylamine (0.5 mL, 3.5 mmol) in DMF (5 mL) was purged for 5 min with argon and added CuI (0.022g, 0.12 mmol). The reaction mixture was heated for Ih at 80 0C and cooled to room temperature. The resulting mixture was concentrated and purified by silica gel chromatography (hexanes/EtOAc 100:0 to 90:10 gradient) to afford the title compound as a yellow solid (0.35 g, 67%).[0161] 1H NMR (500 MHz, DMSO-J6): delta 1.29 (d, J= 6.9 Hz, 6H), 2.38 (s, 3H), 3.47 (qn, J = 6.8 Hz, IH), 7.01 (d, J = 4.1 Hz, IH), 7.32 (t, J = IA Hz, IH), 7.47 (t, J = 1.6 Hz, IH), 7.50 (d, J = 8.4 Hz, 2H), 7.53 (d, J = 1.1 Hz, IH), 7.73 (d, J = 7.8 Hz, IH), 8.04 (d, J = 8.4 Hz, 2H), 8.12 (d, J = 4.0 Hz, IH) [0162] MS (ES+): m/z 450 (M+H)+
