Reaction Steps

tert-Butyl 4-(4-bromo-2,6-dimethylphenylthio)-5-methyl-5H-pyrrolo[3,2-d]pyrimidin-2-yl(4-cyanophenyl)carbamate (0.729 mmol) is combined with pyridine-4-boronic acid (1.46 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.0729 mmol) in a two dram vial. The vial is sealed and flushed with argon. Degassed THF (5.0 mL) and aqueous Na2CO3 (2 M, 1.5 mL, 3.0 mmol) are injected, and the mixture agitated on a shaker at 80° C. for 10 h. The mixture is diluted with ethyl acetate and extracted with aqueous Na2CO3 (0.5 M, ×2). The organic layer is collected, concentrated, and the residue purified by chromatography (SiO2, 1:4 hexanes/EtOAc).
