Suzuki coupling between the pyrazolopyrimidinyl iodide (IX) and the pinacol arylboronate derivative (XI) provides the 3-aryl pyrazolopyrimidine (XII). The N-Boc protecting group of (XII) is then removed under acidic conditions to give aniline (XIII). Acid chloride (XV), prepared by chlorination of 1-methyl-2-indolecarboxylic acid (XIV) is finally coupled to aniline (XIII) to furnish the title amide.
