Adding some certain compound to certain chemical reactions, such as: 15205-15-9, name is 2-Chloro-6-fluorobenzylamine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 15205-15-9. 15205-15-9
Step 7: (S) -tert-Butyl (1- (4- ( (2-chloro-6-fluorobenzyl) carbamoyl) -2- (3- (cyclopropylmethoxy) -4- (difluoromethoxy) phenyl) oxazol-5-yl) ethyl) carbamate[0525]To 10 mL of dichloromethane were added (S) -5- (1- ( (tert-butoxycarbonyl) amino) ethyl) -2- (3- (cyclopropylmethoxy) -4- (difluoromethoxy) phenyl) oxazole-4-carboxylic acid (0.3 g, 0.64 mmol) , 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride (183.36 mg, 0.96 mmol) and 1-hydroxy-7-azabenzotriazole (130.56 mg, 0.96 mmol) . To the resulting solution were added (2-chloro-6-fluorophenyl) methanamine (0.1 mL, 0.77 mmol) and N, N-diisopropylethylamine (0.33 mL, 1.92 mmol) , and the mixture was stirred at rt for 22 hours. The reaction mixture was washed with water (20 mL ¡Á 3) . The organic layer was dried over anhydrous sodium sulfate. The organic solvent was removed and the residue was purified by silica gel column chromatography (PE/EtOAc (v/v) 5/1) to give the title compound as a white solid (264 mg, 67) .[0526]1H NMR (400 MHz, CDCl3) : delta ppm 7.59 (dd, J1 8.3 Hz, J2 1.9 Hz, 1H) , 7.54 (d, J 1.8 Hz, 1H) , 7.47 -7.45 (m, 1H) , 7.27 (d, J 4.6 Hz, 1H) , 7.24 (d, J 8.4 Hz, 1H) , 7.10 -7.06 (m, 1H) , 6.71 (t, JF-H 75.0 Hz, 1H) , 5.32 -5.25 (m, 1H) , 4.87 -4.84 (m, 2H) , 3.98 (d, J 6.9 Hz, 2H) , 1.56 (d, J 7.0 Hz, 3H) , 1.45 -1.43 (m, 9H) , 1.38 -1.34 (m, 1H) , 0.73 -0.68 (m, 2H) , 0.44 -0.40 (m, 2H) .
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 2-Chloro-6-fluorobenzylamine.
