1-Propanol → 4-(5-Bromo-2-propoxy-phenyl)-6-chloro-pyrimidin-2-ylamine

Participants

Reaction Steps

To the stirred solution of 2-(2-amino-6-chloro-pyrimidin-4-yl)-4-bromo-phenol (0.060 g, 0.20 mmol), 1-propanol (0.036 g, 0.60 mmol), and triphenylphosphine (0.157 g, 0.60 mmol) in tetrahydrofuran (5.0 ml) was added diethyl azodicarboxylate (0.104 g, 0.60 mmol). After stirring for 16 hours, the mixture was concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel eluting with ethyl acetate-hexane (1:6) to provide 4-(5-bromo-2-propoxy-phenyl)-6-chloro-pyrimidin-2-ylamine (0.036 g, 52% yield) as a white powder.
