With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.5908-62-3,1,1-Dioxo-isothiazolidine,as a common compound, the synthetic route is as follows.
General procedure: 5-(l -(3-Bromobenzyl)- 5-methyl-lH-l,2,4-triazol-3-yl)-3-(4-(trifluoromethoxy) phenyl)- 1,2,4-oxadiazole (40 mg, 0.0833 mmol), Cs2C03 (54 mg, 0.167 mmol), XPhos (16 mg, 0.0333 mmol), Pd2(dba)3 (15 mg, 0.0167 mmol), and N’,N’-dimethylethane-l,2-diamine were placed in a microwave reaction vessel and dioxane (1 mL), which had been degassed by bubbling N2 through it for 10 min, was added. The reaction was heated by microwave irradiation at 120 C for 1 h. Purification by prep-HPLC (MeCN/H20 30% -70% MeCN containing 0.1% TFA) afforded N,N-dimethyl-2- ((3-((5-methyl-3-(3-(4-(trifluoromethoxy)phenyl)-l,2,4-oxadiazol-5-yl)-lH-l,2,4- triazol-l-yl)methyl)phenyl)amino)ethanaminium trifluoroacetate as a thin film (1.5 mg, 4%).
5908-62-3 1,1-Dioxo-isothiazolidine 642157, athiazolidine compound, is more and more widely used in various.
