YieldReaction ConditionsOperation in experiment
With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In water; toluene; at 100℃;Inert atmosphere; Methyl boronic acid (2.30 g, 38.4 mmol), c2 (7.95 g, 30.7 mmol) and K2CO3(8.48 G, 61.4 mmol) dissolved in toluene (150 ml) and water (30 ml) in. The mixture through the degassing by bubbling by nitrogen for 30 minutes, and add four trityl phosphorus palladium Pd (PPh3)4(1.78G,1 . 53 mmol). The mixture is then maintained at 100 C lower overnight. After the completion of the reaction, the mixture is cooled to room temperature, toluene extraction, and for brine and washed. The organic solution is filtered and evaporation. The crude product by column chromatography, using ethyl acetate in heptane gradient mixture (20% to 65%) purification. The white powder product by the heptane recrystallized three times, to get to the colorless crystal e2. In a 1 L three-opening in the bottle, adding hydration iridous chloride (14.1 g, 40 mmol) and compound e2 (33.02 g, 170 mmol), then add 300 mL2 - ethoxy ethanol and 100 ml of water, the mixture at reflux overnight under a nitrogen atmosphere. After the reaction, cooling to room temperature, the methanol precipitation and filtration and washing, drying to obtain intermediate A2 (24.00 g, yield 90%).
