Application of 771583-81-4, These common heterocyclic compound, 771583-81-4, name is 4-Chloro-2-(trifluoromethyl)benzylamine, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
5-((4- (ethylsulfonyl) benzyl) carbamoyl) -2-fluorobenzoic acid (150.0 mg, 0.4 mmol), HATU (234.0 mg, 0.6 mmol), and DIPEA (211.8 mg, 1.6 mmol) ) Dissolved in tetrahydrofuran (10mL), stirred at room temperature for 0.5 hours, then added 4-chloro-2- (trifluoromethyl) benzylamine (129.1mg, 0.6mmol), reacted at room temperature for 4 hours, then added an appropriate amount Water and extracted three 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 (100.0 mg, yield: 42%).
The synthetic route of 771583-81-4 has been constantly updated, and we look forward to future research findings.
