YieldReaction ConditionsOperation in experiment
With hydrogen;Pb-CaCO3; In tetrahydrofuran; Example B4 Preparation of 4-chloro-6-iodo-1.2-phenylenediamine 1.5 g of <strong>[123158-75-8]4-chloro-2-iodo-6-nitroaniline</strong> together with 50 ml of tetrahydrofuran and 10 ml of 1-propanol are initially introduced into a stirred autoclave. 5 mg of FeCl2.4H2 O and 0.3 g Pt/Pb-CaCO3 catalyst are added to the solution, and hydrogenation is carried out at 130 C. and 20 bar of hydrogen. After the hydrogenation has come to a standstill, the reaction mixture is cooled to room temperature, the reactor is rendered inert with nitrogen and the catalyst is filtered off. After filtration, the solvent is removed by distillation to give 1.3 g of 4-chloro-6-iodo-1,2-phenylenediamine as a crude product. 1 H-NMR (CDCI3, 300MHz) 3.56 ppm (s, 2H, broad); 3.77 ppm (s, 2H, broad); 6.68 ppm (s, 1H); 7.18 ppm (s, 1H).

YieldReaction ConditionsOperation in experiment
336 mg (96%) In (2S)-N-methyl-1-phenylpropan-2-amine hydrate; ethanol; B. Synthesis of 4-chloro-6-iodo-1,2-phenylenediamine: To a stirred mixture of <strong>[123158-75-8]4-chloro-2-iodo-6-nitroaniline</strong> (389 mg, 1.305 mMol) in ethanol (10 mL) was added SnCl2 ·2H2 O (1.468 g, 6.526 mMol) in one portion. The mixture was refluxed at 80 C. (oil bath 90 C.) with stirring for 0.5 h to form a clear solution and then refluxing was continued for another 0.5 h. The solution was cooled to room temperature and ice water (20 g) was added. The pH was adjusted to pH~7 and the mixture was extracted with ethyl acetate. The extract was dried over MgSO4, and evaporated to dryness to give 336 mg (96%) of 4-chloro-6-iodo-1,2-phenylenediamine, as a brown solid. NMR (1 H, CDCl3): delta3.536 (s, 2H); 3.763 (s, 2H); 7.165 (d, 1H, J=1.8 Hz); 6.671 (d, 1H, J=1.8 Hz).
