Reaction Steps

Additional compounds were prepared following the protocol of Scheme 32, either by substituting pyridine-3-boronic acid with an appropriate boronic acid or by substituting the 5-bromo-7-azaindole with 5-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine and reacting with a suitable aryl or heteroaryl halide (i.e. coupling with the boronic acid ester on the azaindole, and the halide on the group to be coupled to the 5-position of the azaindole). The following compounds were prepared by this procedure:
