実験手順

88 mg of [3-(2-bromo-4,5-difluorobenzyloxy)propyl]dimethylamine, 80 mg of potassium carbonate, 5 μl of water and 12 mg of [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) dichloride are added to a solution of 150 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 2 ml of ethanol under argon. The mixture is heated at 120° C. for 60 min. The solid is subsequently filtered off through kieselguhr with suction, and the filtrate is evaporated to dryness in vacuo. The residue is dissolved in 1 ml of DMSO and chromatographed by means of preparative HPLC (Agilent). The product fractions obtained are subsequently evaporated and freeze-dried.
