Participants

Reaction Steps

5-bromoindolin-2-one (23.6 mg, 0.111 mmol), N-(6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)naphthalen-2-yl)thiophene-3-carboxamide (75.0 mg, 0.198 mmol), Fibercat palladium catalyst (Johnson-Matthey, 36.3 mg), and K2CO3 (2 M in water, 0.25 ml, 0.5 mmol) were combined in a microwave reaction vessel and 1,4-dioxane (1.1 ml) was added. The reaction tube was sealed and heated in the microwave (CEM microwave) at 60 Watts and 80 C, first for 10 minutes, and then for 20 minutes. The reaction was cooled to room temperature, diluted with water (5 ml), and extracted with dichloromethane (3×10 ml) and EtOAc (6×10 ml). The organic extracts were combined, dried over sodium sulfate, filtered, concentrated, and purified two times on HPLC (10%->95% MeCN/water with 0.1% TFA) to afford title compound (3.8 mg, 9%). MS (ESI pos. ion) m/z: 385 (M+H). Calc'd Exact Mass for C23H16N2O2S: 384.
