Adding a certain compound to certain chemical reactions, such as: 138588-22-4, 3-(Pyridin-2-yl)-1,2,4-thiadiazol-5-amine, 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, 138588-22-4, blongs to pyridine-derivatives compound. Product Details of 138588-22-4
3-Pyridin-2-y]-[l ,2,4]thiadiazol-5-ylamine (50 mg, 0.28 mmol), 4~phenoxybenzoic acid (120 mg, 0.56 mmol), and l -[is(dimethyiamino)methylene]-lH-l,2,3-triazolo[4,5-b]pyridinium 3-oxid hexafluorophosphate (128 mg, 0.34 mmol) was placed in a vial. Then dissolved in DMF (3 mL, anhydrous), added N,N-diisopropylet ylamine (98 ,uL, 0.56 mmol), and stirred at 50 C for 16 h. The reaction was diluted with water and extracted with EtOAc (x 3). The combined organic layers were dried and concentrated onto celite. Purified by normal phase chromatography (solvent A CC12, solvent B CH2Cl2/MeOH. NH4OH 90: 10: 1, gradient from 0 – 50% B). Collected the desired product (25.2 mg, 0.0674 mmol, 24%). JH NMR (400 MHz, DMSO-t e) 6 ppm 7.1 1 (d, J-8.83 Hz, 2 H) 7.16 (d, J-7.66 Hz, 2 H) 7.23 – 7.31 (m, 1 H) 7.43 – 7.56 (m, 3 H) 7.98 (td, J=7.75, 1.73 Hz, i H) 8.24 (d, J-8.74 Hz, 3 H) 8.72 (d, J=4.34 Hz, 1 H) 13.71 (br. s., 1 H); LCMS (M/Z): M-H-f 375.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,138588-22-4, its application will become more common.
