실험 절차
A suspension of 2-amino-6-(3,4-dimethoxyphenyl)-pyrido[3,2-d]pyrimidin-4(3H)one (100 mg, 0.34 mmol) and phosphorus pentasulfide (163 mg, 0.37 mmol) in pyridine (10 ml) was refluxed for 4 hours. The solvents were evaporated in vacuo. The residue was re-suspended in a small amount of water and filtered off, yielding the title compound which was used without any further purification and which was characterised as follows: MS (m/z): 315 ([M+H]+, 100).
