YieldReaction ConditionsOperation in experiment
73.9% With potassium acetate; bis(dibenzylideneacetone)-palladium(0); tricyclohexylphosphine In 1,4-dioxane; toluene at 20 - 102℃; for 71 h; Inert atmosphere That is, under nitrogen, to an 1L flask equipped with a stirrer& cooling tube, Pd (dba)2 21.26g (2.19mmol), tricyclo hexylphosphine / toluene 20percent solution 9.23 g (6.57 mmol) and dehydrated dioxane430mL were put and stirred for 30 minutes at a liquid temperature of 20 ~ 23 . To there, potassium acetate 10.8g (110mmol), bis (pinacolato)diboron 20.4g (80.3mmol) and 3- (4-chloro phenyl) pyridine 14.2g (~73.Ommol) were added while rinsing with 20~ 30mL dehydrated dioxane and wasrefluxed for 30 hours at a liquid temperature of 80 . Since the reaction did not show little progress, it was once cooledto 30 .Pd (dba) 2 21.23g (2.14mmol), tricyclo with the addition of hexyl phosphine / toluene 20percent solution 9.19g (6.55mmol) to, for 30 minutes at a liquid temperature of 30 , followed by liquid It was refluxed for 40 hours at temperature 102 .Thiswas then cooled to room temperature and pure water 300 mL was added and stirred,and the reaction solution was extracted with ethyl acetate 400 mL and water dustwas further extracted with ethyl acetate 200mL. The organic layers were combinedand washed twice with saturated brine 300 mL and liquid separated, and driedover sodium sulfate. After removal of sodium sulfate by filtration, it was evaporatedto give an oil 37.2g of orange color. The resulting oil was purified by silicagel column chromatography (silica gel 200 g, ethyl acetate / hexane = 1/3) to obtaina fraction 111.6 g (GC purity 92.7percent) and a fraction 210.4g (GC purity of 70.3percent) whichcompose compound 2 as main component. fraction 1 was further purified by silicagel column purification (silica gel 200 g, ethyl acetate / hexane = 1/3) togive the compound 210.7g (GC purity 94.8percent). fraction 2 was further purified by silicagel column purification (silica gel 150 g, ethyl acetate / hexane = 1/3) toobtain compound 2 was obtained 5.2 g (GC purity 96.5percent). Total yield was 15.9g(GC purity 95percent, 53.9mmol). The yield was 73.9percent. Compound 2 was a yellow oil
