実験手順

Potassium tert-butoxide (4 mL; 1M in THF) was added to a suspension of 6-Chloro-4-[1,2,4]triazol-1-yl-pyrido[3,2-d]pyrimidin-2-ylamine (1 g) and 2-methoxyethanol (0.32 mL) in DCM (50 mL). After stirring at room temperature for 10 minutes, the mixture was diluted with DCM (100 mL) and washed with brine. The organic layer was dried over Na2SO4 and concentrated to afford 6-chloro-4-(2-methoxy-ethoxy)-pyrido[3,2-d]pyrimidin-2-ylamine as a beige solid (0.91 g, yield: 90%) which was characterized by its mass spectrum as follows: MS (m/z) 225.0 [M+H]+.
