YieldReaction ConditionsOperation in experiment
79% Intermediate 12B; 4-bromo-3-chlorobenzene-l,2-diamine; 4-Bromo-3-chloro-2-nitroaniline (4.78 g, 19.01 mmol) was dissolved in ethanol (112 mL). Tin (II) chloride (14.42 g, 76 mmol) was added, and the resulting mixture was stirred at reflux for 12 hours. The mixture was cooled to room temperature, poured into water, and adjusted to pH 5 with saturated sodium bicarbonate solution. The resulting solid was filtered and rinsed well with ethyl acetate. The filtrate was washed with water and brine, dried over Na2SOt, filtered and concentrated in vacuo. The crude product was purified by column chromatography on silica gel using a solvent gradient of 0-50% EtOAc in hexane to give the title compound (3.32 g, 79%). .H NMR (400 MHz, CDC13) δ ppm 6.94 (d, 1H), 6.51 (d, J= 7.0, 1H), 3.87 (br s, 2H), 3.46 (br s, 2H). I
70% With tin(ll) chloride; In ethanol; at 70℃; 5.25 g (20.877 mmol) of the compound from example 43A was dissolved in 120 ml ethanol and 18.84 g (83.508 mmol) of tin(II) chloride dihydrate was added. The mixture was stirred overnight at 700C. After cooling, water was added, it was made weakly alkaline with saturated aqueous sodium hydrogen carbonate solution and extracted three times with ethyl acetate. The combined organic phases were dried over sodium sulfate and concentrated in a rotary evaporator at reduced pressure. The residue was dried under high vacuum. We obtained 4.40 g (purity 74%, 70% of theor.) of the target compound.LC-MS (method 3): R, = 1.42 min; MS (EIpos): m/z = 221 [M+H]+.
6.7g With tin(II) chloride dihdyrate; In ethanol; for 4h;Reflux; Inert atmosphere; A mixture of 10 g of <strong>[1000573-99-8]4-bromo-3-chloro-2-nitroaniline</strong> and 36 g of SnCl2.2H20 in EtOH (150 mL) was heated at reflux for 4 hours. The reaction mixture was allowed to cool, then was quenched carefully with sat. aq. NaHCCb solution until slightly basic. The thick mixture was extracted with EtOAc. Dried (Na2S04), concentrated and purified by column chromatography (silica gel, 0-40 % EtOAc in hexanes) to afford 6.7 g of 4-bromo-3-chlorobenzene-l,2-diamine as a tan solid.
6.7 g With tin(II) chloride dihdyrate; In ethanol; for 4h;Reflux; [0659] A mixture of 10 g of <strong>[1000573-99-8]4-bromo-3-chloro-2-nitroaniline</strong> and 36 g of SnC12.2H20 in EtOH (150 mL) was heated at reflux for 4 h. The reaction mixture was allowed to cool and was then quenched carefully with saturated aqeuous NaHCO3 solution until slightly basic. The thick mixture was extracted with EtOAc, dried withNa2SO4, concentrated, and purified by ISCO (0-40 % EtOAc in Hexanes) to afford 6.7 g of the title compound as tan solid.
