To a suspension of 5-phenyl-[1,4]oxazepane hydrochloride (0.07 g, 0.33 mmol) and 2-chloro-3-methyl-6-(pyrimidin-4-yl)-3H-pyrimidin-4-one (0.07 g, 0.30 mmol) in tetrahydrofuran (2 mL) in a sealed tube was added triethylamine (0.14 mL) at room temperature. The mixture was heated to 150° C. under microwave irradiation and stirred for 15 min. After cooling to room temperature, the reaction mixture was poured into water and extracted with chloroform. The extracts were dried over anhydrous sodium sulfate and concentrated. The residue was purified by flash column chromatography on silica gel (chloroform/methano=10/1 as an eluant) to yield 2-(5-phenyl-[1,4]oxazepane-4-yl)-3-methyl-6-pyrimidin-4-yl-3H-pyrimidin-4-one (A071) (0.07 g, 0.20 mmol, 66%) as a white solid.
