Related Products of 54730-35-7, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 54730-35-7, name is 3,5-Dichloro-4-methylaniline, This compound has unique chemical properties. The synthetic route is as follows.
Preparation 9; 5-bromo-l,3-dichloro-2-methylbenzene; Suspend 3, 5 -dichloro-4-methylaniline in 48% HBr (5 mL) and water (5 mL) and heat with a heat gun until the mixture is near the boiling point. Cool the slurry to room temperature and then cool to 00C with an ice/brine bath. Add dropwise a solution of sodium nitrite (109 mg, 1.58 mmol) in water (2 mL). After the addition is complete, stir the reaction an additional 15 min in the cold bath. Add a solution of CuBr (1.08 g, 7.53 mmol) in 48% HBr (2 mL) and heat the rapidly stirring reaction to 500C for 1 hour. Cool the reaction to room temperature, dilute with EtOAc and discard the aqueous layer. Wash the organic layer with water and brine, dry with MgSO4, filter through celite and concentrate to an orange residue. Purify the residue by silica gel chromatography eluting with hexanes to afford 164 mg (45%) of the product as a yellow solid.
The chemical industry reduces the impact on the environment during synthesis 3,5-Dichloro-4-methylaniline. I believe this compound will play a more active role in future production and life.
