Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 93919-56-3, name is (4-(Trifluoromethoxy)phenyl)methanamine, A new synthetic method of this compound is introduced below., Application In Synthesis of (4-(Trifluoromethoxy)phenyl)methanamine
Step 2 Nitro-4-(4-trifluoromethoxy-benzylamino)-benzoic acid allyl ester; 5.0 g of 4-fluoro-3-nitro-benzoic acid allyl ester (22 mmol) were dissolved in 100 ml ethanol. 4.25 g of 4-(trifluoromethoxy)-benzylamine (22 mmol) were added and stirred at room temperature for 1 h. The product was extracted from methylenchloride/water and dried over sodium sulfate. The crude product was crystallized from isopropyl ether to result in yellow crystals (7.5 g). MS(ISP): 397.2 (M+H)+.
The synthetic route of 93919-56-3 has been constantly updated, and we look forward to future research findings.
