Ammonium Hydroxide → 1-(6-Aminopyridin-3-yl)ethan-1-one

Participants

Reaction Steps

1-(6-Chloropyridin-3-yl)-ethanone (230 mg, 1.5 mmol), 1 mL 28% aq NH4OH, and catalytic CuSO4.5H2O were heated to 130° C. in a sealed tube for 5 h. The mixture was cooled, diluted with 20 mL water, and washed with 2×25 mL EtOAc. The combined organics were washed with brine, dried (MgSO4), filtered, and evaporated.
