YieldReaction ConditionsOperation in experiment
With tetrakis(triphenylphosphine) palladium(0); potassium acetate; In 1,4-dioxane; at 80.0℃; for 2.0h;Inert atmosphere; Steps 3 and 4: preparation of ethyl 2-(2-cyano-6-methox pyridin-3-yl)-3-ethox acrylate (6D): A mixture of 3D (1.0 g, 4.7 mmol), bis(pinacolato)diboron (1.7 g, 7.0 mmol), Pd(dppf)Cl2 (360 mg, 0.5 mmol), and KOAc (1.0 g, 10.0 mmol) in dioxane (50 mL) was degassed and stirred at 80C for 2 h under N2. After the mixture was cooled to r.t. and compound 5D (1.30 g, 4.8 mmol), Pd(PPh3)4 (550 mg, 0.5 mmol), K2C03 (1.4 g, 10.0 mmol), and H20 (10 mL) was added, and the mixture was stirred at 90C for 3 h under N2. The mixture was extracted with EtOAc (200 mL X 2), washed with sat NaCl (100 mL), dried over Na2S04, concentrated and purified by column (PE : EtOAc = 3:1) to give the product as white solid (600 mg, 48%).
