YieldReaction ConditionsOperation in experiment
61% With tetrakis(triphenylphosphine) palladium(0); sodium carbonate; In 1,4-dioxane; water; at 90℃; for 10h;Inert atmosphere; 5-Amino-3-bromo-1-isopropyl-1H-pyrazole-4-carbonitrile (2.29 g, 0.01 mol) was added to the reaction flask.2-amino - benzooxazole-5-boronic acid hydrochloride (2.57g, 0.012mol),Sodium carbonate (5.3 g, 0.05 mol) and dioxane-water (10-50 mL),After stirring, tetrakistriphenylphosphine palladium (0.92 g, 0.80 mmol) was added, and the mixture was evacuated and filled with argon gas.This was repeated three times, heated to 90 C, and stirred under argon for 10 hours.Cool, concentrate to dryness under reduced pressure, add water (100 mL), shake, filter, rinse dry,Mix the solids with silica gel and quickly pass through the column.White solid5-amino-3-(2-aminobenzo[d]oxazole-5-yl)-1-isopropyl-1H-pyrazole-4-carbonitrile (4a) 1.72 g,Yield: 61%.
