Reaction Steps

A solution of 2-amino-9-chloro-10-iodo-5,7-dihydro-6H-pyrimido[5,4-d][1]benzazepin-6-one (1.66 g, 4.29 mmol) and propargyl(dimethylamine) (0.74 mL, 6.89 mmol) in triethylamine (7 mL) and DMF (7 mL) was degassed with argon. To this solution was added bis(triphenylphosphine)palladium(II)chloride (0.30 g, 0.43 mmol) and copper iodide (0.163 g, 0.86 mmol). The reaction mixture was allowed to stir at 75° C. overnight. After the reaction mixture was allowed to cool to rt, water was added. The precipitate that formed was filtered and dried to give 2-amino-9-chloro-10-[3-(dimethylamino)prop-1-yn-1-yl]-5,7-dihydro-6H-pyrimido[5,4-d][1]benzazepin-6-one (1.61 g, 98%) as a brown solid. LCMS (FA): m/z=342 (M+H).
