HCID 13102700, compound → 3-Pyridinamine, 6-(3,4-dichlorophenoxy)-

Participants

Reaction Steps

The 2-(3,4-dichlorophenoxy)-5-nitropyridine described above was divided into 4 portions of 23.7 g each, and each portion was then hydrogenated in absolute ethanol employing a palladium catalyst as well known in the art. After removal of the catalyst, the ethanol filtrates were combined and evaporated to dryness. The residue which remained was diluted with isopropyl alcohol and hexane and then chilled. The resulting solid was collected by filtration and vacuum dried to give 70.8 g of 2-(3,4-dichlorophenoxy)-5-pyridinamine as a rose colored powder, m.p. 78°-79.3° C.
