1-[5-(4-Nitro-phenyl)-furan-2-yl]-ethanone → HCID 2302841, compound

Participants

Reaction Steps

A mixture of 58 g (0.25 mole) of methyl 5-(p-nitrophenyl)-2-furyl ketone, 2 tsp. of Raney Ni and 750 ml of ethanol was shaken under hydrogen pressure for one hour with the theoretical amount of H2 being absorbed. An additional 2000 ml of ethanol was added to the reaction mixture. The mixture was heated to reflux and the catalyst was removed by filtration. The filtrate was treated with ethereal HCl and the resulting solid was filtered and air-dried to yield 41 g (8.15%) of methyl 5-(p-aminophenyl)-2-furyl ketone. An analytical sample was prepared by drying a sample at room temperature in the vacuum pistol, m.p. scinters above 160°.
