Reaction Steps

A sealed tube containing 4-chloro-2-pyridinamine (4 g, 31.2 mmol), (2,2-dimethyl-1,3-dioxolan-4-yl)methanol (8.4 g, 60.6 mmol), and sodium (1.46 g, 63.5 mmol) was heated at 145° C. for 8 hours. The mixture was cooled to ambient temperature; water (25 mL) and dichloromethane (50 mL) were added. The organic phase was separated, dried with sodium sulfate, and concentrated under reduced pressure. The resulting residue was purified by chromatography on silica-gel to give 4-((2,2-dimethyl-1,3-dioxolan-4-yl)methoxy)pyridin-2-amine as a pale yellow solid (5.6 g).
