N-(4-(4-(methylamino)-3-nitrophenoxy)pyridin-2-yl)-2-(4-ethylpiperazin-1-yl)acetamide → N-(4-(3-amino-4-(methylamino)phenoxy)pyridin-2-yl)-2-(4-ethylpiperazin-1-yl)acetamide

Participants

Reaction Steps

The mixture containing N-(4-(4-(methylamino)-3-nitrophenoxy)pyridin-2-yl)-2-(4-ethylpiperazin-1-yl)acetamide in methanol with a catalytic amount of 10% Pd/C poisoned with lead was hydrogenated until the disappearance of the yellow color. The reaction was then filtered to remove the catalyst and concentrated to yield N-(4-(3-amino-4-(methylamino)phenoxy)pyridin-2-yl)-2-(4-ethylpiperazin-1-yl)acetamide as a brown oil. HPLC=2.00 min; MS: MH+=385.
