反应详情

To a solution of 3-(nitro-4-n-butylamino)-benzophenone (5.96 g.; 0.02 mole) in ethanol (200 ml.) is added palladium on charcoal (5%; 0.1 g.). The mixture is hydrogenated until theoretical uptake of hydrogen has occurred (about 3 hours) and then let stand at room temperature overnight. The reaction mixture is filtered to remove the catalyst and the filtrate concentrated under vacuum to afford 4.75 g. (88.6% yield) of 3-amino-4-n-butylaminobenzophenone.
