A solution of 8-bromo-6-(4-chlorophenyl)-1-methyl-5,6-dihydro-4H-benzo[b][1,2,4]triazolo[4,3-d][1,4]diazepine (30 mg, 0.08 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-amine (35 mg, 0.16 mmol), Tetrakis(triphenylphosphine)palladium(0) (10 mg) and Cs2CO3 (60 mg, 0.16 mmol) in dioxane (5 mL) and water (1 mL) was heated at 120° C. under microwave for 20 min. The reaction mixture was concentrated to give the crude product, which was purified by prep-TLC (DCM:MeOH=12:1) to afford 5-(6-(4-chlorophenyl)-1-methyl-5,6-dihydro-4H-benzo[b][1,2,4]triazolo[4,3-d][1,4]diazepin-8-yl)pyridin-2-amine (9.3 mg, yield 29%).
