Reaction Steps

A mixture of 3-amino-6-bromopyridine (865 mg, 5.00 mmol), 2-hydroxypyridine (475 mg, 5.00 mmol), N,N′-dimethylethylenediamine (0.215 mL, 2.00 mmol) and K2CO3 (1.38 g, 10.0 mmol) in dioxane (8 mL) was degassed with Argon before being charged with CuI (190 mg, 1.00 mmol). The mixture in a sealed tube was heated at 110° C. overnight. After being cooled down, H2O and nBuOH were added. The organic phase was separated, and concentrated in vacuo to give 1-(5-aminopyridin-2-yl)pyridin-2(1H)-one (316 mg).
