clear yellow to brown liquid after melting | [Uses]
In industrial applications, 5-bromo-2-methylaniline is often used as a chemical intermediate for the synthesis of drugs, dyes or other chemicals. | [Synthesis]
The general procedure for the synthesis of 2-amino-4-bromotoluene from 4-bromo-2-nitrotoluene was as follows: first, 4-bromo-1-methyl-2-nitrobenzene (5 g, 23.14 mmol, 1.00 eq.), ethyl acetate (100 mL), and SnCl2-H2O (20 g) were added to a 250 mL round-bottom flask. The reaction mixture was stirred at 30 °C overnight. Upon completion of the reaction, the pH of the reaction solution was adjusted to 10 with 5 mol/L sodium hydroxide solution.Subsequently, the reaction solution was extracted with ethyl acetate (3 x 30 mL) and the organic layers were combined. The organic phase was sequentially washed with brine (3 × 50 mL), dried over anhydrous sodium sulfate and finally concentrated under reduced pressure. After the above steps, 4 g (93% yield) of 5-bromo-2-methylaniline was obtained as a brown oily product. | [References]
