4-[2-(4-aminophenyl)propan-2-yl]aniline

Conditions: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 294 g of 2,2-bis(4-nitrophenyl)propane (1.03 mol; prepared as in step c) was charged in an autoclave along with 2 liters of 1,4-dioxane and 25 g of 5% palladium on carbon. The autoclave was purged with nitrogen, then heated at 60° C. for six hours under 500 psi hydrogen pressure. The product mixture was filtered to remove the catalyst, then stripped of solvent by rotary evaporation at reduced pressure. The solid residue was triturated with a small amount of hexane, then collected and dried by suction filtration under a blanket of nitrogen to afford 224.0 g (0.99 mol, 96% of theory) of 4,4'-isopropylidenedianiline (bisaniline-A), m.p. 130-131.5° C. The autoclave was purged with nitrogen The product mixture was filtered to remove the catalyst stripped of solvent by rotary evaporation at reduced pressure The solid residue was triturated with a small amount of hexane collected dried by suction filtration under a blanket of nitrogen
