1,2-Dichloro-4-nitrobenzene → 3,4-dichloro-N-(propan-2-yl)aniline

Participants

Reaction Steps

480.0 g (2.5 mol) of 3,4-dichloronitrobenzene were reacted in 2500 ml of butyl acetate under the reaction conditions described in Example 1 with 10 g of sulfited platinum catalyst F1OP. After the solvent had been distilled off in vacuo, the residue was fractionated to give 431.0 g of N-isopropyl-3,4-dichloroaniline at a purity of 98.9% (GC) in the boiling range 143° to 148° C. (13.33 to 16 bar), which corresponds to a yield of 84.5% of theory.
