Conditions

Temperature: 120 °C

Procedure

74 mg of (2-bromo-5-fluorophenyl)methanol, 100 mg of potassium carbonate, 1 ml of water and 15 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 3 ml of ethanol under argon. The mixture is heated at 120° C. for min; the hot mixture is filtered through kieselguhr, and the filtrate is evaporated in vacuo. The residue is purified by reverse-phase column chromatography.
