24243-71-8, Adding some certain compound to certain chemical reactions, such as: 24243-71-8, name is Propane-1-sulfonamide, 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 24243-71-8.
A mixture of 2′-chloro-6′-(2,6-dimethylphenoxy)-1,5-dimethyl43,4′-bipyridin]-6(1H)-one (52 mg, 0.15 mmol), propane-1-sulfonamide (46 mg, 0.37 mmol), Pd2(dba)3 (7 mg, 5%), X-Phos (11 mg, 15%) and Cs2CO3 (68 mg, 0.21 mmol) was diluted with 1,4 dioxane (1 mL). After the mixture was purged with nitrogen for 5 min, it was sealed and heated to 90 C. for 3 hr. The cooled mixture was poured into H2O and extracted with EtOAc. The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure. The resulting residue was purified by prep-HPLC (10 min_10-95% ACN_0.1% formic acid, 20 ml/min) to afford the title compound (36 mg, 55%) as a tan solid. 1H NMR (400 MHz, DMSO-d6) delta 0.69-0.76 (m, 3H) 1.32-1.43 (m, 2H) 2.03-2.12 (m, 9H) 2.62-2.71 (m, 2H) 3.54 (s, 3H) 6.62 (s, 1H) 6.98 (s, 1H) 7.03-7.15 (m, 3H) 7.72 (s, 1H) 8.22 (s, 1H) 10.36 (br s, 1H). LCMS (M+H)+442.
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 24243-71-8.
