Versuchsvorschrift

To the crude 2-amino-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine-4-carbonitrile (prepared as in Method 11) (25 mg, 0.13 mmol) solution in dioxane (1.8 mL) in a pressure vessel, was added (6-bromo-2-morpholin-4-yl-pyrimidin-4-yl)-quinolin-3-yl-amine (19.4 mg, 0.05 mmol) and aq. Na2CO3 (2 M, 0.6 mL, 1.2 mmol). After purging the reaction mixture with argon, dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II) dichloromethane adduct (10.3 mg, 0.01 mmol) was added in one portion. The pressure vessel was sealed and the mixture was heated in a microwave at 120° C. for 900 seconds. The crude mixture was filtered and concentrated under reduced pressure. The crude product was purified by reverse phase preparative HPLC to give 2-amino-5-[2-morpholin-4-yl-6-(quinolin-3-ylamino)-pyrimidin-4-yl]-isonicotinonitrile (4.4 mg, 20%). LC/MS (m/z): 425.0 (MH+), Rt 2.03 minutes.
