Reaction Steps

A mixture of 2-fluoro-4-iodoaniline (3.00 g, 12.6 mmol), 2-hydroxypyridine 1-7 (1.20 g, 12.6 mmol), 8-hydroxyquinoline (0.184 g, 1.26 mmol) and K2CO3 (3.49 g, 25.3 mmol) in DMSO (20 mL) was degassed with Ar before being charged with CuI (0.241 g, 1.27 mmol). The mixture in a sealed tube was heated at 130° C. overnight. After being cooled down to room temperature, H2O and nBuOH were added. The organic phase was separated, concentrated in vacuo to give 1-(4-amino-3-fluorophenyl)pyridin-2(1H)-one as a solid (2.31 g).
