Procedure

A mixture of 2-amino-9-chloro-5,7-dihydro-6H-pyrimido[5,4-d][1]benzazepin-6-one (0.36 g, 1.38 mmol), 3-(5-bromo-2-methoxypyridin-3-yl)-N,N-dimethylpropan-1-amine (0.38 g, 1.38 mmol), xphos (0.047 g, 0.099 mmol), and tris(dibenzyllideneacetone)dipalladium(0) (0.023 g, 0.026 mmol) in a sealed microwave tube was evacuated and purged with nitrogen three times. To the solids were added tert-butyl alcohol (3.6 mL) and t-BuOK (1M in t-BuOH, 2.63 mL) via syringe. The mixture was stirred well and then subjected to microwave irradiation (150 watts) while heating at 150° C. for 45 min. The reaction mixture was then poured into water (25 mL) with vigorous stirring. The precipitate that formed was filtered, washed with water, and air dried. The residue was purified by column chromatography to give 9-chloro-2-({5-[3-(dimethylamino)propyl]-6-methoxypyridin-3-yl}amino)-5,7-dihydro-6H-pyrimido[5,4-d][1]benzazepin-6-one (0.125 g, 18%).
