1-N,1-N,2-三甲苯-1,3-二胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 57 g of 3-dimethylamino-2-methyl-aniline, 1.15 liters of acetone, 36.6 g of KSCN and 43.8 ml of benzoylchloride are refluxed together for 3 hours. After cooling to ambient temperature the reaction mixture is poured onto 2.4 kg of crushed ice. The precipitate obtained is heated to 60° C. for 2 hours together with 85 g of KOH, 85 ml of water and 255 ml of ethanol. After the addition of 850 ml of water the ethanol is distilled off under reduced pressure. After the resulting precipitate has been worked up, 72 g of N-(3-dimethylamino-2-methylphenyl)-thiourea are obtained. The precipitate obtained is distilled off under reduced pressure

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 73 g of N,N-dimethyl-2-methyl-3-nitroaniline are dissolved in 800 ml of methanol and hydrogenated at 20° C. under 5 bar of hydrogen using Raney nickel as catalyst. 57 g of 3-dimethylamino-2-methylaniline are obtained.
