Reaction Steps
In a 2-5 mL Smith Process Vial, 6-(3,5-dimethylisoxazol-4-yl)-4-iodo-1H-benzo[d]imidazol-2(3H)-one (100.0 mg 0.282 mmol), (2-methylnaphthalen-1-yl)boronic acid (176.0 mg, 0.946 mmol, 3.36 equiv), PEPPSI-iPr (19.2 mg, 0.028 mmol, 0.1 equiv) and Cs2CO3 (337.0 mg, 1.126 mmol, 4 equiv) were placed. The mixture was suspended in 1,4-dioxane (1.5 mL) and water (0.5 mL) under N2. The mixture was heated at 150° C. for 75 min using microwave reactor (Biotage Optimizer). After an aqueous work up, the crude product was purified by a silica-gel column chromatography (hexane/EtOAc 20:80) to give 6-(3,5-dimethylisoxazol-4-yl)-4-(2-methylnaphthalen-1-yl)-1H-benzo[d]imidazol-2(3H)-one.
