Synthetic Route of 641571-13-3, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 641571-13-3 as follows.
3-(4-methyl-1H-imidazol-1-yl)-5-(trifluoromethyl)benzoic acid (12 mg, 0.0436 mmol), 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium 3-oxid hexafluorophosphate (22.6 mg, 0.059 mmol), and TEA (7.2 mg, 0.078 mmol) were dissolved in DMF (0.2 ml), the solution was stirred at 45 C. for 30 minutes, the compound F (10.2 mg, 0.039 mmol) was then added, and the solution was stirred at 45 C. for 12 hours. After the reaction was completed, ethyl acetate was added and the reaction mixture was washed with a saturated aqueous NaCl solution. The organic layer was dried with sodium sulfate anhydrous and filtered, and then the solvent was removed under reduced pressure. The residue was crystallized to obtain a target compound 3-(4-methyl-1H-imidazol-1-yl)-N-(3-(2-oxo-2,3-dihydro-1H-thieno[3,4-b][1,4]diazepine-4-yl)phenyl)-5-(trifluoromethyl)benzamide (15.6 mg, 78%). 1H NMR (400 MHz, DMSO-d6) delta 10.71 (1H, s), 10.53 (1H, s), 8.49 (1H, s), 8.43-8.42 (2H, m), 8.26 (1H, s), 8.22 (1H, s), 8.06 (1H, dd, J=8.2, 1.4 Hz), 7.79 (1H, d, J=8.0 Hz), 7.73 (1H, s), 7.58-7.54 (2H, m), 7.04 (1H, d, J=4.0 Hz), 3.61 (2H, s), 2.20 (3H, s). (Exact mass 509.11, m/z 510.1186)
