Procedure

A mixture of EXAMPLE 187A (0.079 g), dicyclohexyl(2′,6′-dimethoxybiphenyl-2-yl)phosphine (0.016 g), and palladium acetate (0.0045 g) in tetrahydrofuran (1 mL) was stirred at room temperature for 5 minutes. To this mixture was added (2-(1,3-dioxolan-2-yl)ethyl)zinc(II) bromide (0.6 mL). The reaction mixture was stirred overnight. The solvent was removed, and the residue was purified by reverse phase Prep HPLC. The desired fractions were combined, and the organic solvent was partially removed. The resulting mixture was treated with saturated aqueous NaHCO3, extracted with ethyl acetate, dried over MgSO4, filtered, and concentrated to give the title compound. 1H NMR (500 MHz, dimethylsulfoxide-d6) δ 11.14 (s, 1H), 8.37 (s, 1H), 8.00 (s, 1H), 7.55 (br s, 1H), 7.52 (d, 1H), 7.33-7.39 (m, 4H), 7.08 (br s, 1H), 7.04 (d, 2H), 6.83 (dd, 1H), 6.62 (d, 1H), 6.38 (s, 1H), 6.15 (d, 1H), 4.85 (t, 1H), 3.87-3.89 (m, 2H), 3.76-3.79 (m, 2H), 3.04 (s, 4H), 2.91-2.94 (m, 2H), 2.11-2.15 (m, 4H), 1.88-1.91 (s, 4H), 1.39 (t, 2H), 0.92 (s, 6H).
