YieldReaction ConditionsOperation in experiment
With tris-(dibenzylideneacetone)dipalladium(0); caesium carbonate; 4,5-bis(diphenylphos4,5-bis(diphenylphosphino)-9,9-dimethylxanthenephino)-9,9-dimethylxanthene; In 1,4-dioxane; at 140℃; for 0.666667h;Inert atmosphere; Microwave irradiation; To 2-choro-5-nitro-3-trifluoromethypyridine (056 g, 2.48 mmo) and isothiazoHdine 1,1- dioxide (060 g, 496 mmo) in 1,4-dioxane (12 m) were added Cs2003 (0.81 g, 2.48 mmo) and argon was bubbed though the mixture for 10 mm. Then Xantphos (287 mg, 0,50 mrnoD and Pd2(dba)3 (114 mg, 0.124 mmoD were added. The reaction mixture was stirred for 40 mm at 140°C in a microwave oven. The mixture was fi?tered through a pad of C&ite and the sovent was evaporated. The crude product was purified by flash co?umn chromatography on sihca ge (cyciohexane/AcOEt 100/0 to 50/50) to afford 2-(5- nitro-3-(trifluoromethy)pyridmn-2-y)isothiazoidine 1,1-dioxide. M/z = 312 [M+H]+, Rt = 0.87 mm (U PLC Method 32).
