実験手順

Potassium carbonate (1.00 g, 7.28 mmol) was added to a flask charged with 2-amino-8-ethyl-4-methyl-6-((trimethylsilyl)ethynyl)pyrido[2,3-d]pyrimidin-7(8H)-one (1.09 g, 3.64 mmol) in anhydrous methanol (15 mL). The reaction was stirred at room temperature under nitrogen for 16 h. The reaction was concentrated to one half volume and the yellow precipitate collected by vacuum filtration to afford 2-amino-8-ethyl-6-ethynyl-4-methylpyrido[2,3-d]pyrimidin-7(8H)-one.
