3-Bromo-7-(trifluoromethyl)imidazo[1,2-a]pyrimidine → 3-[2-Fluoro-3-(pyridin-3-yl)phenyl]-7-trifluoromethylimidazo[1,2-alpha]pyrimidine

Participants

Reaction Steps

3-Bromo-7-trifluoromethylimidazo[1,2-α]pyrimidine was coupled with 2-fluoro-3-(pyridin-3-yl)benzeneboronic acid as described in Example 1 to give 3-[2-fluoro-3-(pyridin-3-yl)phenyl]-7-trifluoromethylimidazo[1,2-α]pyrimidine as an off-white solid. Bis-hydrochloride salt (from ethyl acetate/ethanol): δH (360 MHz, DMSO) 7.62 (2H, dd, J 7 and 7), 7.85-7.96 (3H, m), 8.36 (1H, s), 8.58 (1H, d, J 8), 8.86 (1H, dd, J 5 and 1), 9.14 (1H, s), 9.33 (1H, dd, J 7 and 3); m/z (ES+) 359 (M++H).
