Procedure
3-Bromo-7-trifluoromethylimidazo[1,2-α]pyrimidine was coupled with 2-[2,6-difluoro-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)phenyl]pyridine as described in Example 1 to give 3-[2,4-difluoro-3-(pyridin-2-yl)phenyl]-7-trifluoromethylimidazo[1,2-α]pyrimidine as a pale yellow solid. Bis-hydrochloride salt (from ethyl acetate/ethanol): δH (360 MHz, DMSO) 7.55 (1H, dd, J 9 and 9), 7.62-7.68 (2H, m), 7.86-7.96 (2H, m), 8.14 (1H, ddd, J 8, 8 and 2), 8.38 (1H, s), 8.84 (1H, d, J 5), 9.30 (1H, dd, J 7 and 3); m/z (ES+) 377 (M++H).
