N1-(4-Chlorophenyl)benzene-1,2-diamine synthesis

8synthesis methods
To a mixture of EtOH (100 ml) and NH4C1 saturated solution (15 ml), N-(4-chlorophenyl)-2-nitrobenzenamine (5.0 g, 20.1 mmol) was added, followed by iron powder (4.0 g). The reaction mixture was heated at 70 °C for 2h. The solid was filtered, and the filtrate was extracted by EA (100 mL x 3) and dried over Na2S04. After the solvent was removed, the mixture was purified by Combi-flash (PE: EA = 5 : 1) to give N1-(4-Chlorophenyl)benzene-1,2-diamine (4.1 g, 93.2 percent) as a light yellow solid.

Yield:68817-71-0 94%

Reaction Conditions:

with Aminoiminomethanesulfinic acid;sodium hydroxide in ethanol;lithium hydroxide monohydrate at 50; for 1.5 h;Reagent/catalyst;Solvent;Temperature;

Steps:

General procedure for the synthesis of 4 in Table 3

General procedure: A mixture of 3 (10 mmol) and NaOH (4.0 g, 100 mmol) was prepared in EtOH (5 mL) and H2O (15 mL). TDO (5.4 g, 50 mmol) was added in batches within 15 minutes to the mixture followed by stirring at 50 °C. After completion of the reaction as indicated by TLC, cooled to room temperature, the precipitated solid was filtered out and washed with water to obtain compound 4.
