with potassium carbonate;copper in 1-methyl-pyrrolidin-2-one for 70 h;Heating / reflux;
Steps:
1
Synthesis of a compound 2 A three-neck flask was charged with 56.5 g of p-phenylenediamine, 495 g of p-nitrochlorobenzene (1), 173.7 g of potassium carbonate, 750 ml of 1-methyl-2-pyrrolidone and 10 g of a copper powder and the mixture was stirred under heating and refluxing for 70 hours as it was. The reaction mixture was cooled to ambient temperature to obtain crystals, which were then washed with 1-methyl-2-pyrrolidone, washed with water and then dried by air, to obtain 297.3 g of the target compound 2 (yield: 96%). The mass-spectrum of this compound was measured, to find that M = 592. Melting point: 300°C or more.
