Reaction Steps

A mixture of Example A1 (2.55 g, 10.13 mmol) and NH4Cl (5.42 g, 101 mmol) in THF (250 mL) and MeOH (250 mL) was treated with zinc dust (6.63 g, 101 mmol), stirred at RT for 3 h, the solids removed via filtration and the filtrate concentrated to dryness and purified by silica gel chromatography to provide 5-((2-chloropyridin-4-yl)oxy)pyridin-2-amine (1.41 g, 63% yield).
