Conditions

Temperature: 120 °C

Procedure

148 mg of (2-bromo-4,5-difluorobenzyl)diethylamine, 170 mg of potassium carbonate, 7 μl of water and 17 mg of [1,1′-bis(diphenylphosphino)ferrocene]-palladium(II) dichloride are added to a solution of 170 mg of [2-amino-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinazolin-4-yl]-(1,3-dihydroisoindol-2-yl)methanone in 4 ml of ethanol under argon. The mixture is heated at 120° C. for 30 min; the hot mixture is filtered through kieselguhr, and the filtrate is evaporated and purified by chromatography (reversed phase HPLC).
