clear light yellow to yellow liquid after melting | [Uses]
4-Amino-3-chlorobenzotrifluoride serves as a starting material for the synthesis of 5-chloro-N-(2-chloro-4-(trifluoromethyl)phenyl)-2-hydroxybenzamide [3]. | [Definition]
ChEBI: 2-Chloro-4-(trifluoromethyl)aniline is a member of (trifluoromethyl)benzenes. | [Synthesis]
The general procedure for the synthesis of 3-chloro-4-aminobenzotrifluoride and 3-amino-4-chlorobenzotrifluoride from 3,4-dichlorobenzotrifluoride was as follows:
1. 1050 mL of N-methylpyrrolidone and 102 g of anhydrous activated potassium fluoride were added to an autoclave followed by 377 g of 3,4-dichlorobenzotrifluoride.
2. 158 g of ammonia was vented from a pressure tank into the reactor at ambient temperature.
3. the reaction mixture was heated to 245-250°C over a period of 2 hours, at which time the reactor pressure reached 30-32 kg/cm2 .
4. continued to add excess ammonia from the pressure tank to maintain reactor pressure of 38-40 kg/cm2 at 245-250°C liquid temperature.
5. maintain the reaction mixture at 245-250°C and 38-40 kg/cm2 pressure for 8 hours.
6. cool the reaction mixture to ambient temperature, vent and recover unreacted ammonia.
7. Filter the reaction mixture and separate the products by fractional distillation. Based on the consumed 3,4-dichlorobenzotrifluoride, 3-chloro-4-aminobenzotrifluoride in 77% yield and 3-amino-4-chlorobenzotrifluoride in 13% yield were obtained. | [References]
