Bromoisoindolin-1-one (11.5 mg, 0.0542 mmol), N-(6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)naphthalen-2-yl)thiophene-3-carboxamide (43.3 mg, 0.114 mmol), Fibercat palladium catalyst (Johnson-Matthey, 21.0 mg), and K2CO3 (2 M in water, 0.1 ml, 0.2 mmol) were combined in a microwave reaction vessel and 1,4-dioxane (0.55 ml) was added. The reaction tube was sealed and heated in the microwave (CEM microwave) for 10 minutes at 50 Watts and 80 C. The reaction was cooled to room temperature, diluted with water (10 ml), and extracted with dichloromethane (6×5 ml). The organic extracts were combined, dried over sodium sulfate, filtered, and concentrated. The crude material was washed with 15:1 hexanes/EtOAc and then purified on HPLC (10%->95% MeCN/water with 0.1% TFA) to afford title compound (4.9 mg, 24%). MS (ESI pos. ion) m/z: 385 (M+H). Calc'd Exact Mass for C23H16N2O2S: 384.
