97% | With tin(II) chloride dihdyrate; In ethanol; for 3.0h;Reflux; | 3-Chloro-5-methyl-phenylamine. An ethanol solution (75 mL) containing <strong>[16582-38-0]1-chloro-3-methyl-5-nitro-benzene</strong> (5.0 g, 29 mmol) are added with SnCl2.2H2O (32.8 g, 146 mmol). The reaction mixture was reflux for 3.0 h. The solution was concentrated under vacuum, and the residue was re-dissolved in aqueous NaOH, filtered, and extracted with EtOAc. The organic layer was collected, washed with brine, dried over MgSO4, and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel to give 3-chloro-5-methyl-phenylamine (4.0 g) as light yellow solids in 97% yield: 1H NMR (500 MHz, CDCl3) delta 6.56 (s, 1H), 6.48 (s, 1H), 6.36 (s, 1H), 3.66 (bs, 2H), 2.23 (s, 3H); ESI-MS: m/z 141.7 (M+H)+. |

The organic layer was collected, washed with brine, dried over MgSO4(s), and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel to give 3-chloro-5- methyl-phenylamine (4.0 g) as light yellow solids in 97% yield: 1H NMR (500 MHz, CDCl3) delta 6.56 (s, 1 H), 6.48 (s, 1 H), 6.36 (s, 1 ), 3.66 (s, 2 H), 2.23 (s, 3 H); ESI-MS: m/z 141.7 (M + H)+. |
80% | 3-Chloro-5-nitrotoluene (45 g, 0.241 mol) and ethanol (500 ml) were mixed in a 2 litter four-neck flask. The mixture was cooled to about 4 ° C. A solution of tin chloride monohydrate (217.67 g, 0.965 mol) in 200 ml of ethanol was added dropwise to the mixture over 2 hours, while the reaction mixture was maintained at 10 ° C. or lower. Then the reaction product mixture was stirred at room temperature for 2 hours and poured into 2500 ml of iced water. It was neutralized with sodium hydroxide and filtered with a nutsche filled with sellaite. The residue was washed with ethyl acetate. The intended product was obtained with ethyl acetate from the filtrate liquid. Then the extract liquid and the washing liquid were jointed. The mixture was washed with water and then a saturated salt water and dried with magnesium sulfate. Concentrated, it was treated by distillation at a reduced pressure to obtain 28.0 g of a yellow liquid (production yield 80%). B.p.: 85-92 ° C./0.4 kPa or lower (3 Torr or lower) 1H-NMR, 500 MHz, in CDCl3 (delta) 6.56 (bs, 1H), 6.48 (dd, JI, J2=1.3 Hz, 1H), 6.36 (bs, 1H), 3.64 (bs, 2H), 2.22 (s, 3H) |
80% | Example LII; 3-chloro-5-methyl-aniline; 2.4 g of <strong>[16582-38-0]3-chloro-5-nitro-toluene</strong> are dissolved in 35 ml of ethanol, combined with 15.8 g tin dichloride-dihydrate and refluxed for 3 hours. The solvent is eliminated in vacuo, the residue is taken up in 4 M sodium hydroxide solution and filtered through kieselguhr. The filter cake is washed thoroughly with ethyl acetate. The aqueous phase is extracted 3 times with ethyl acetate and the combined organic phases are washed with saturated sodium chloride solution and dried on magnesium sulphate. The solvent is eliminated in vacuo and the residue is chromatographed on silica gel (cyclohexane/ethyl acetate 81 :15 to 70:30). Yield: 1.59 g (80 % of theory) Mass spectrum (ESI+): m/z = 142 [M+H]+ | |
c. 3-Chloro-5-methylaniline Using a procedure similar to that described in Example 20a except starting with <strong>[16582-38-0]3-chloro-5-nitrotoluene</strong>, the title compound was obtained (85%)as a yellow solid; MS(CI): 142 (M+H). 300-MHz 1 H NMR (DMSO-d6): 6.56 (s, 1H), 6.48 (s, 1H), 6.36 (s, 1H), 3.65 (br s, 2H), 2.22 (s, 3H). | ||
With ethanol; tin(IV) chloride; at 85℃; for 2.0h; | To a solution of l-chloro-3-methyl-5 -nitrobenzene (1.61 g, 9.38 mmol) in EtOH (30 ml) was added tin chloride (8.90 g, 46.9 mmol). The reaction was heated at 85C for 2 h and was then quenched with INNaOH (50 mL) and extracted with EtOAc (100 mL). The aqueous layer was extracted with EtOAc (2x). The combined organic phase was washed with brine, dried over anhydrous MgS04, filtered and concentrated in vacuo. The residue was purified by chromatography on silica (Eluant: Hexane:EtOAc = 100:0 ~ 40:60) to afford the title compound 3-chloro-5-methylaniline. LCMS calc. = 142.03; found = 141.92 (M+H)+. 1H NMR (500 MHz, CDCI3): delta 6.56 (s, 1 H); 6.49 (s, 1 H); 6.37 (s, 1 H); 3.65 (brs, 2 H); 2.23 (s, 3 H). |
