실험 절차

A solution of 2-(3,5-dimethoxyphenyl)acetate (6) (440 mg, 2.40 mmol), 4-amino-2-(methylthio)pyrimidine-5-carbaldehyde (4) (605 mg, 2.88 mmol) and potassium carbonate (662 mg, 4.8 mmol) in DMF (30 mL) was stirred at 110° C. for 3 hours. The reaction was monitored by LCMS. The reaction mixture was diluted with H2O (30 mL), and extracted by EtOAc (3×40 mL). The combined organic layers were washed with water and brine, dried over sodium sulfate, filtered and concentrated. The residue was purified by column chromatography (silica gel, petroleum ether/EtOAc=2:1) to afford 6-(3,5-dimethoxyphenyl)-8-methyl-2-(methylthio)pyrido[2,3-d]pyrimidin-7(8H)-one (7) (683 mg, 83%) as a white solid. MS (ES+) C17H17N3O5S requires: 343. found: 344 [M+H]+.
