Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 15205-11-5, name is 2-Chloro-4-fluorobenzylamine, This compound has unique chemical properties. The synthetic route is as follows., COA of Formula: C7H7ClFN
To a stirred mixture of 1-(2-chloro-4-fluorophenyl)methanamine (80 mg, 0.501 mmol, 1 equiv.) and 4-chloro-5-(4-oxopiperidin-1-yl)-2,3-dihydropyridazin-3-one (114.12 mg, 0.501 mmol, 1.00 equiv.) in DMF (5 mL) were added 1-azido-4-nitrobenzene (115.18 mg, 0.702 mmol, 1.4 equiv.) and Zn(OAc)2 (91.98 mg, 0.501 mmol, 1 equiv.) at room temperature. The resulting mixture was stirred for 16 h at 60 degrees C. The reaction was monitored by LCMS.The mixture was allowed to cool down to room temperature. The mixture was purified by reverse phase flash with the following conditions (Column:C18,330 g; Mobile Phase A: Water/0.05% NH4HCO3, Mobile Phase B:ACN; Flow rate:80 mL/min;Gradient: 35%B to 50%B in 15 min; Detector,220nm and 254nm) to afford crude product. The crude product (30 mg) was purified by Prep-HPLC with the following conditions (Column: XBridge Shield RP18 OBD Column, 5um,19*150mm; Mobile Phase A: Water(10MMOL/L NH4HCO3), Mobile Phase B: ACN; Flow rate: 25 mL/min; (1701) Gradient: 5% B to 16% B in 1 min; 254/220 nm; Rt: 7.47 min) to afford 4-chloro-5-[1-[(2- chloro-4-fluorophenyl)methyl]-1H,4H,5H,6H,7H-[1,2,3]triazolo[4,5-c]pyridin-5-yl]-2,3- dihydropyridazin-3-one(8.3mg,4.19%) as a white solid
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 15205-11-5.
