実験手順

A suspension of tert-butyl 4-(4-(8-oxa-3-azabicyclo[3.2.1]octan-3-yl)-6-chloro-1,3,5-triazin-2-yl)piperazine-1-carboxylate (1.0 g, 2.4 mmol), 4-aminophenylboronic acid, pinacol ester (0.69 g, 3.2 mmol), and tetrakis(triphenylphosphine) palladium (0.28 g, 0.24 mmol) in aqueous 2 M sodium carbonate solution (3 mL) and 1:1 ethanol/toluene (12 mL) was irradiated in the microwave at 120° C. for 1 hour. After cooling, the biphasic mixture was extracted thrice with ethyl acetate. The extracts were washed with saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, filtered, and concentrated to dryness under reduced pressure to give the title compound.
