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. Formula: C7H6N4S
3-Pyridm-2-yl-[l,2,4]thiadiazol-5-yIamine (50 mg, 0.28 mmol) and p-chlorobenzoic acid (44 mg, 0.28 mmol) were mixed in 1 mL of anhydrous dimethvlformamide, to which solution was added N,N-diisopropylethylamine (0.1 mL, 0.58 mmol) followed by addition of 1 – [his(dimethylammo)methylene]~ 1H- 1 ,2,3-triazolo[4,5-b]pyridinium 3 -oxide hexafluorophosphate (1 14 mg, 0.30 mmol). The mixture was stirred under nitrogen at room temperature overnight. The reaction mixture was partitioned between ethyl acetate and water. The aqueous layer was extracted with ethyl acetate. The combined organic layer was dried over sodium sulfate, filtered and concentrated. The crude product was purified by flash chromatography to obtain Compound 7 as a white solid (53.5 mg, 60%). NMR (400 MHz, DMSO-rfe) delta ppm 7.36 – 7.64 (m, 1 H) 7.69 (d, J=8.69 Hz, 2 H) 7.91 – 8.10 (m, 1 H) 8.12 – 8.34 (m, 3 H) 8.72 (d, J=4.00 Hz, 1 H); LCMS (M/Z): M+HT’ 317.
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.
