実験手順

To a mixture of 7-chloropyrido[3,2-d]pyrimidin-4(1H)-one (250 mg, 1.377 mmol) in toluene (12 mL) were added DIPEA (0.73 mL, 4.20 mmol) and phosphorus oxychloride (0.391 mL, 4.27 mmol), and the reaction was stirred at reflux for 1 hour. After cooling to RT, the reaction mixture was concentrated to provide the title compound. LC/MS (ESI+) m/z=200 (M+H).
