A degassed mixture of 6-chloro-3-(4-piperidin-1-ylmethylphenyl)-9H-dipyrido[2,3-b;4′,3′-d]pyrrole (74.4 mg, 0.197 mmol), 2-aminopyrimidine-5-boronic acid, pinacol ester (45.8 mg, 0.207 mmol), and [1,1′-bis(diphenylphosphino)ferrocene] dichloropalladium(II) complex with dichloromethane (1:1) (8.1 mg, 9.87 umol, 5.0 mol %) in acetonitrile (0.74 mL) and 1M aqueous potassium carbonate solution (0.74 mL) was heated under microwave irradiation (140° C.) for 30 minutes. Further portions of the boronate ester (1.0 eq) and catalyst (5 mol %), acetonitrile (0.74 mL), and 1M aqueous potassium carbonate solution (0.74 mL) were added and the mixture heated under microwave irradiation (140° C.) for an additional 30 minutes. The mixture was concentrated in vacuo and the residue dissolved in water and DMF, and acidified with 10% (v/v) sulfuric acid. The resultant solid was removed by filtration and the filtrate concentrated in vacuo. The resultant residue was dissolved in DMSO and purified by preparative HPLC [0-30% MeCN/water modified with 0.1% formic acid] to afford an orange fluffy solid (5.1 mg, 14%). LCMS (Method E): RT=5.45 min, M+H+=436.
