Versuchsvorschrift

A mixture of 2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-carbaldehyde 10 (100 mg, 0.35 mmol), 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-indazole (70) (95 mg, 0.39 mmol) and sodium carbonate (112 mg) were suspended in toluene (2.5 mL), ethanol (1.5 mL) and water (0.7 mL). To this was added bis(triphenylphosphine)palladium(II) chloride (13.5 mg) and the reaction vessel was flushed with argon. The reaction mixture was microwaved at 120° C. for 1 h and then partitioned between DCM and water, the organic layer was washed with brine, dried over magnesium sulfate, filtered and evaporated in vacuo. The resulting residue was purified using flash chromatography to yield 2-(1H-indazol-4-yl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-carbaldehyde 11 (97 mg).
