2-Methoxyethanol → 6-Chloro-4-(2-methoxyethoxy)pyrido[3,2-d]pyrimidin-2-amine

Participants

Reaction Steps

Potassium t-butoxide (4 mL, 4 mmol; 1 M in THF) was added to a suspension mixture of 6-chloro-4-[1,2,4]triazol-1-yl-pyrido[3,2-d]pyrimidin-2-ylamine (1 g, 4 mmol) and 2-methoxyethanol (0.32 mL, 4 mmol) 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 the pure title compound as a beige solid (0.91 g, yield 90%) which was characterised as follows: MS (m/z) 225.0 [M+H]+.
