Isopropanol → 6-Chloro-4-[(propan-2-yl)oxy]pyrido[3,2-d]pyrimidin-2-amine

Participants

Reaction Steps

Potassium tert-butoxide (4.0 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 (1.0 g) and 2-propanol (0.313 mL) in DCM (50 mL). After stirring at room temperature for 30 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-propoxy)-pyrido[3,2-d]pyrimidin-2-ylamine as a yellow solid (0.65 g, yield: 67%) which was characterized by its mass spectrum as follows: MS (m/z) 239.1 [M+H]+.
