Versuchsvorschrift

To a microwave vial containing 6-(thiophene-2-carboxamido)naphthalen-2-yl trifluoromethanesulfonate (0.100 g, 0.2 mmol), in 1,4-Dioxane (3 mL), was added isoquinolin-5-ylboronic acid (0.129 g, 0.8 mmol), Fibrecat catalyst (0.005 g, 5% by wt.), and Potassium Carbonate (2 M, 0.50 mL, 1 mmol). The vial was capped and placed into CEM Microwave for 10 minutes at 80° C., while supplying 50 Watts of power through power-max. The mixture was diluted with DCM (2 mL) and water (2 mL). The aqueous layer was extracted with DCM (3×10 mL). The combined organics was dried over sodium sulfate, filtered, and concentrated in-vacuo. The crude was purified from reverse-phase HPLC. This gave a yellow colored amorphous solid, which was titled product (0.078 g, 0.2 mmol). MS (ESI pos. ion) m/z: 381 (M+H).
