Reaction Steps

To a solution of 2-(3,4-dimethoxy-phenylamino)-9-iodo-5H,7H-benzo[b]pyrimido[4,5-d]azepin-6-one (I-30) (300 mg, 0.614 mmol) in 4 mL DMF at 22° C. was added dichlorobis(triphenylphosphine)palladium (15 mg, 0.02 mmol), copper iodide (9 mg, 0.05 mmol), and triethylamine (0.34 mL, 2.45 mmol). The solution was degassed with argon, and stirred at 22° C. for 1 h. (Trimethylsilyl)acetylene (120 mg, 1.22 mmol) was added and the solution was stirred at 22° C. for 2 h. Water was added to the reaction mixture, and the resulting precipitate was filtered and purified by silica gel chromatography (ISCO, elution with 30-100% ethyl acetate in hexanes) to give I-33-a (180 mg, 64%): MS m/z═459 (M+H).
