Participants

Reaction Steps

128 mg of ammonium chloride and 67 mg of iron powder were added to a suspension of 143 mg of 3-chloro-2,4-bis(pyridin-3-yloxy)-6-nitroaniline in 8 ml of methanol and 4 ml of water, and the reaction liquid was heated under reflux for 2 hours. The reaction liquid was filtered, and the solvent was evaporated away under reduced pressure.
