4-(5-amino-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-(isopropylamino)pyrimidine-5-carbonitrile (0.204 g, 0.455 mmol) in DCM (12 mL) was treated with phenylboronic acid (0.111 g, 0.910 mmol, 2.0 Eq), copper acetate (0.124 g, 0.682 mmol, 1.5 Eq), pyridine (0.074 mL, 0.910 mmol, 2.0 Eq) and 4 Angstrom molecular sieves (0.600 g) and the reaction was allowed to stir at room temperature for 16 hours. The reaction mixture was quenched with 4M Ammonia in MeOH (12 mL) and filtered through a plug of celite whilst washing through with further DCM/MeOH. The combined washes were evaporated to dryness and purified by column chromatography (ISCO Companion™, 12 g column, 0-100% EtOAc/Petroleum Ether) to give the title compound as a yellow solid (85 mg, 36%).
