実験手順
(2-chloro-4-morpholinopyrido[3,2-d]pyrimidin-6-yl)methanol 6 (1 g) was reacted with pyridinium chlorochromate (1.1 eq) overnight at room temperature in dichloromethane (25 mL). The reaction was filtered thru celite and run thru a silica plug to get 0.69 g of 2-chloro-4-morpholinopyrido[3,2-d]pyrimidine-6-carbaldehyde as a yellow solid after evaporation.
