Sodium Sulfate → tert-Butyl 2-(3-aminoquinolin-4-ylamino)ethylcarbamate

Participants

Reaction Steps

Platinum on carbon (1 g of 10%) and sodium sulfate (2 g) were added to a slurry of tert-butyl N-[2-(3-nitroquinolin-4-yl)aminoethyl]carbamate (100 g, 0.30 mol) in toluene (500 mL). The mixture was placed under a hydrogen atmosphere at 50 psi (3.4×104 pascals) on a Parr apparatus at ambient temperature overnight. The reaction mixture was filtered. The filtrate was concentrated to provide 73 g of tert-butyl N-[2-(3-aminoquinolin-4-yl)aminoethyl]carbamate as a dark gold oil.
