Procedure

A mixture of 5-chloro-7-morpholinothiazolo[4,5-d]pyrimidine-2-carbaldehyde 43, 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-indazole 1 and sodium carbonate were suspended in toluene, ethanol and water. To this was added bis(triphenylphosphine)palladium(II) chloride 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 5-(1H-indazol-4-yl)-7-morpholinothiazolo[4,5-d]pyrimidine-2-carbaldehyde 55.
