Procedure

8-Iodo-5-phenyl-[1,2,4]triazolo[4,3-a]quinoline (250 mg, 0.67 mmol), 3-mercaptobenzoic acid (120 mg, 0.81 mmol), iPr2NEt (0.36 mL, 2.1 mmol), Pd2dba3 (15 mg, 0.02 mmol), and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (19 mg, 0.03 mmol) were dissolved in 1,4-dioxane and degassed with N2. The reaction was then sealed and heated to 70° C. for 30 minutes, followed by cooling to room temperature, filtration, and concentration to give the desired product, 11a.
