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. 771583-81-4, name is 4-Chloro-2-(trifluoromethyl)benzylamine, A new synthetic method of this compound is introduced below., Formula: C8H7ClF3N
5-((4- (ethylsulfonyl) benzyl) carbamoyl) -2- (2-fluoroethoxy) benzoic acid (200.0 mg, 0.5 mmol), HATU (278.6 mg, 0.7 mmol) and DIPEA (189.0 mg, 1.5 mmol) was dissolved in tetrahydrofuran (10 mL), and after stirring at room temperature for 0.5 hours, 4-chloro-2- (trifluoromethyl) benzylamine (153.6 mg, 0.7 mmol) was added. At room temperature After reacting for 4 hours, an appropriate amount of water was added and extraction was performed 3 times with ethyl acetate. The organic phases were combined and washed with a saturated sodium chloride solution, dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The concentrate was purified by preparative high performance liquid chromatography to obtain the title compound (150.0 mg, yield: 51%) in this step.
The synthetic route of 771583-81-4 has been constantly updated, and we look forward to future research findings.
