Synthetic Route of 7149-75-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 7149-75-9, name is 4-Chloro-3-methylaniline belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
General procedure: The corresponding pyrazinoic acid (5.0 mmol) was dispersed in dry toluene (20 mL) and mixed with 1.5eq. of thionyl chloride (0.55 mL, 7.5 mmol). The reaction mixture was heated to reflux for approximately 1 h. Next, the excess of thionyl chloride was removed by repeated evaporation with dry toluene under vacuum.The crude acyl chloride was dissolved in dry acetone(20 mL) and added drop-wise to a stirred solution of the corresponding aniline (5.0 mmol) with triethylamine(5.0 mmol) in dry acetone (30 mL). The reaction mixture was stirred at ambient temperature for up to 6 h. The completion of the reaction was monitored by TLC (eluent: hexane/ethyl acetate; r =2 : 1). The crude product adsorbed on silica gel by solvent evaporation was purified by flash chromatography(hexane/ethyl acetate gradient elution).The analytical data of the prepared compounds were fully consistent with the proposed structures and are available in the Supplementary Data.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Chloro-3-methylaniline, other downstream synthetic routes, hurry up and to see.
