Procedure

A mixture of 2-chloro-6-(4-methyl-piperazin-1-yl methyl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (72) (100 mg, 0.27 mmol), indole-4-boronic acid (1.1 eq., 48 mg), sodium hydrogen carbonate (3 eq., 69 mg) and bis(triphenylphosphine)palladium(II) chloride (0.05 eq., 10 mg) in toluene (2.5 mL), ethanol (1.5 mL) and water (0.7 mL) was flushed with argon and heated under microwave irradiation at 120° C. for 1 hour. The reaction mixture was partitioned between dichloromethane and water, 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 the title compound 61 (23 mg, 19%).
