To a solution of Dimethyl-(2-[3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenoxy]-ethyl)-amine (2 eq, 0.272 mmol, 0.079 g) in dry DME (1 ml) under an inert atmosphere of argon is added 2M Na2CO3 (3 eq, 0.408 mmol, 0.204 ml) followed by (5″-Bromo-[2,2′;4′,3″]terpyridin-6′-yl)-cyclopropyl-amine (Example 1.26) (1 eq, 0.136 mmol, 50 mg) and PdCl2dppf (0.1 eq, 0.014 mmol, 11 mg). The reaction mixture is heated using microwave radiation at 90° C. for 90 minutes. The reaction mixture is dissolved in EtOAc and washed with water. The organic solvent is reduced in vacuo and the residue is purified by reverse phase column chromatography (Isolute™ C18, 0-40% acetonitrile in water—0.1% TFA). The appropriate fractions by HPLC are combined and concentrated in vacuo. The resulting residue is dissolved in MeOH and loaded onto a SCX-2 cartridge eluting with MeOH followed by 2M NH3 in MeOH. The methanolic ammonia fractions are combined, concentrated in vacuo and dried under vacuum to afford the title compound; [M+H]+ 452.
