実験手順
2-(2-Chloro-benzylamino)-6H-pyrido[4,3-d]pyrimidin-5-one 8 (3.00 g, 10.5 mmol) was dissolved in POCl3 (30 mL) and stirred at 90° C. for 15 h. The reaction mixture was carefully poured into ice water and the pH was adjusted to 8 adding 2 N NaOH solution. The precipitate formed was filtered off and dried in vacuo. The product was purified by crystallization from diethyl ether to yield in a colorless solid (3.18 g, 10.4 mmol, 100%).
