4-chloro-1-N-cyclohexylbenzene-1,2-diamine

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

Procedure: 34.5 g (0.15 mol) of 2-amino-4-chloro-N-cyclohexylaniline were refluxed in 500 ml of diethyl oxalate for 4 h. After cooling, the precipitate was filtered off with suction, washed with n-pentane and dried to yield 26.8 g (63%) of the product. Melting point 265°-266° C. After cooling the precipitate was filtered off with suction washed with n-pentane dried

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

Procedure: 41.6 g (0.16 mol) of 4-chloro-N-cyclohexyl-2-nitroaniline were dissolved in 400 ml of ethanol and, after addition of 4.2 g of Raney nickel, hydrogenated under 1 bar at 25° C. The mixture was then filtered and the filtrate was concentrated under reduced pressure to yield 37.3 g (100%) of the product. at 25° C The mixture was then filtered the filtrate was concentrated under reduced pressure
