Versuchsvorschrift

A mixture of (S)-ethyl 2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate (106.5 mg, 0.214 mmol), 2-(1-piperazinyl)-pyridine-4-boronic acid, pinacol ester (93 mg, 0.322 mmol), Pd(PPh3)4 (25 mg, 0.02147 mmol) and 2M potassium carbonate (0.321 mL, 0.642 mmol) in anhydrous dioxane (1.0 mL) was sparged with nitrogen for 5 minutes, then heated in microwave for 1 h at 100° C. Reaction mixture was diluted with ethyl acetate, washed with brine, dried (MgSO4), filtered, concentrated and used in next step without further purification. LCMS-ESI+: calc'd for C36H36ClN4O3S: 579.2 (M+H+); Found: 579.1 (M+H+).
