Procedure

6,2′-Difluoro-5′-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-biphenyl-2-carbonitrile was coupled to 2-(7-bromoimidazo[1,2-b][1,2,4]triazin-3-yl)propan-2-ol in 32% yield using a similar procedure to that described in Example C, step f, to give a yellow solid: mp 206° C.; 1H NMR (360 MHz, CDCl3) δ1.71 (6H, s), 3.28 (1H, br s), 7.37-7.66 (4H, m), 8.15 (2H, m), 8.26 (1H, s), 8.78 (1H, s); MS (ES+) mn/z 392 [M+H]+. Anal. Found: C, 64.66; H, 3.93, N, 17.71%. Required for C21H15F2N5O: C, 64.45; H, 3.86; N, 17.89%.
