N-{2-[2-(methylsulfonyl)ethoxy]ethyl}-3-nitroquinolin-4-amine → N4-{2-[2-(methylsulfonyl)ethoxy]ethyl}quinoline-3,4-diamine

Participants

Reaction Steps

Solid Pt/C (0.9 g of 5%) was added to a suspension of N-{2-[2-(methylsulfonyl)ethoxy]ethyl}-3-nitroquinolin-4-amine (9 g, 26.5 mmol) in acetonitrile (133 mL) in a Parr vessel. The vessel was placed on a shaker and then pressurized with hydrogen to 50 psi (3.4×105 Pa). After 3 hours the reaction mixture was purged with nitrogen and then filtered through a layer of CELITE filter agent. The filter cake was washed with acetonitrile (200 mL) until the washes were clear. The filtrate was concentrated under reduced pressure to provide N4-{2-[2-(methylsulfonyl)ethoxy]ethyl}quinoline-3,4-diamine as a yellow oil.
