2-bromo-4-(2,4-dichlorophenyl)-5-(4-methyl-1H-imidazol-2-yl)-1,3-thiazole (55 mg, 0.141 mmol), N-[4-(trimethylstannyl)pyridin-2-yl]acetamide (64 mg, 0.214 mmol) were dissolved in 1,4-dioxane (3.4 mL). Lithium chloride (18.1 mg, 0.427 mmol), copper(I) iodide (8.14 mg, 0.0427 mmol) and tetrakis(triphenylphosphine)palladium(0) (8.23 mg, 0.00712 mmol) were added under atmosphere of argon. The reaction mixture was heated at 90° C. for 7 hours. LCMS indicated complete conversion. Solvent was evaporated and the residue was purified using preparative HPLC to afford 15 mg of the title compound (24%). LCMS; (AA) ES+ 444, 446. 1H NMR (400 MHz, d1-chloroform) δ: 8.79-8.70 (m, 1H), 8.43 (s, 1H), 8.35-8.28 (m, 1H), 7.62-7.59 (m, 2H), 7.50 (d, J=8.25 Hz, 1H), 7.43 (dd, J=8.23, 2.01 Hz, 1H), 2.24 (s, 3H), 2.20 (s, 3H).
