Discovery of 3-Chloro-4-(trifluoromethyl)aniline

According to the analysis of related databases, 445-13-6, the application of this compound in the production field has become more and more popular.

Reference of 445-13-6, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 445-13-6 as follows.

General procedure: A substituted aniline (3.0 mmol) and CDI (3.0 mmol) were dissolvedin anhydrous dichloromethane (15 mL) and the reaction was stirred atroom temperature for 1 h under a nitrogen atmosphere. The solvent wasthen removed under reduced pressure, yielding the crude carbamoylimidazolesas solids. The carbamoylimidazoles were then dissolved indichloromethane (5 mL), and added to a solution of amine 13a or 13b(2.0 mmol) in dichloromethane (15 mL). The reaction was then left tostir for 1 h at room temperature. Dichloromethane (50 mL) was thenadded, and the organic layer was washed with water (3×100 mL). Theorganic layer was dried over Na2SO4 and concentrated under reducedpressure. The product was purified on silica gel by step-wise gradientelution with dichloromethane/ethyl acetate (100:0 to 90:10).

According to the analysis of related databases, 445-13-6, the application of this compound in the production field has become more and more popular.
