Sodium Hydroxide → 6-Iodo-4-methylpyridin-3-amine

Participants

Reaction Steps

To a solution of SnCl2.H2O (20.5 g, 108 mmol) in EtOAc (200 mL) was added 2-iodo-4-methyl-5-nitropyridine (5.7 g, 21.6 mmol) in EtOAc (20 mL). Heat was released, and the reaction mixture was kept at reflux for 2 hr. After cooling to rt, the reaction mixture was treated with 50% NaOH (50 mL). Solid was filtered off and washed with EtOAc. The filtrate was washed with brine, dried, and concentrated to afford 2-iodo-4-methyl-5-pyridinamine (5 g, 99%) as a yellow solid.
