YieldReaction ConditionsOperation in experiment
82% With sodium carbonate;bis-triphenylphosphine-palladium(II) chloride; In water; acetonitrile;Inert atmosphere; Microwave irradiation; Step 4: Synthesis of 3,5-Dimethyl-2-(6-phenylnaphthalen-2-yl)pyrazine (abbreviation: Hdm6p2npr)First, into a recovery flask equipped with a reflux pipe were placed 0.24 g of <strong>[38557-72-1]2-chloro-3,5-dimethylpyrazine</strong>, 0.41 g of 6-phenylnaphthalene-2-boronic acid, 0.18 g of sodium carbonate, 0.008 g of bis(triphenylphosphine)palladium(II) dichloride (abbreviation: Pd(PPh3)2Cl2), 10 mL of water, and 10 mL of acetonitrile, and the air in the flask was replaced with argon. This reaction container was irradiated with microwaves (2.45 GHz, 100 W) for 30 minutes, so that heating was performed. Then, the reaction container was cooled to 50 C. or less. Water was added to the reaction solution, and the organic layer was extracted with dichloromethane. The obtained organic layer was washed with water and dried with magnesium sulfate. The solution which had been dried was filtered. The solvent of this solution was distilled, whereby Hdm6p2npr, which is the pyrazine derivative to be produced, was obtained (as a white powder in 82% yield). Note that the microwave irradiation was performed using a microwave synthesis system (Discover, manufactured by CEM Corporation). The synthesis scheme of Step 4 is illustrated in the following (d-4).
