실험 절차

To a solution of 8,8′-(2,5-dichloropyrimidine-4,6-diyl)bis(3-oxa-8-azabicyclo[3.2.1]octane) (1.0 g, 2.7 mmol) in 1:1 ethanol:toluene (10 mL) was added 4-aminophenylboronic acid pinacol ester (0.7 g, 3.2 mmol), 2.0M solution of sodium carbonate (1.2 mL) and tetrakis(triphenylphosphine) palladium (0) (0.3 g, 10 mol %). The reaction was refluxed under nitrogen overnight. The reaction was cooled and water was added (75 mL) and the mixture was extracted 3 times with ethyl acetate. The organics were separated and dried over magnesium sulfate, then filtered through Magnesol™ and concentrated in vacuo to an oil. The crude product was purified via silica gel column with hexanes/ethyl acetate to yield the title compound as a white solid (0.708 g). MS m/z=428 (M+H).
