2-Methylsulfanyl-6H-pyrido[4,3-d]pyrimidin-5-one 6 (3.00 g, 15.5 mmol) and 2-Chlorobenzyl amine 7 (9.40 mL, 77.6 mmol) were stirred at 150° C. for two days. To the recooled mixture Methanol/water (1:1, 100 mL) was added and left at RT overnight. The precipitate was filtered off and dried in vacuo. The product was purified by crystallization from ethanol to yield in a colorless solid (4.00 g, 14.0 mmol, 90%).
