Reaction Steps
A stirred mixture of 2,3-dihydrobenzo[b][1,4]dioxin-6-ol (0.137 g, 0.90 mmol), Cs2CO3 (0.734 g, 2.25 mmol), CuI (0.02 g, 10% w/w), and N2-(6-chloropyrimidin-4-yl)pyridine-2,6-diamine (0.29 g, 0.90 mmol) in NMP (1 mL) was heated at 100° C. for 16 h. The reaction mixture was cooled to rt and slowly added to demineralised water. The solid that precipitated was collected by filtration and was further purified by column chromatography (SiO2, 60-120, pet ether/ethyl acetate, 7/3) to give N2-(6-(2,3-dihydrobenzo[b][1,4]dioxin-6-yloxy)pyrimidin-4-yl)pyridine-2,6-diamine (0.088 g, 29%) as yellow solid.
