To a solution of (S)-methyl 2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate (193 mg, 0.40 mmol) and tert-butyl 4-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)piperazine-1-carboxylate (217 mg, 0.56 mmol) in 1,4-dioxane (3 mL) was added potassium carbonate solution (0.80 mL, 1.6 mmol, 2 M aqueous solution) and Pd(PPh3)4 (23 mg, 0.02 mmol). The reaction mixture was stirred at 105° C. for 3 h. The mixture was diluted with brine (5 mL) and EtOAc (5 mL). The layers were separated, and the organic layer was dried, filtered, and concentrated in vacuo and used without further purification. LCMS-ESI+: calc'd for C36H43ClN3O5S: 664.3 (M+H+); Found: 664.3 (M+H+).
