Imidazo[1,2-a]pyrimidine, 3-(tributylstannyl)-7-(trifluoromethyl)- → 3-[3-([1,2,4]Triazol-1-yl)-phenyl]-7-trifluoromethylimidazo[1,2-a]pyrimidine

Participants

Reaction Steps

1-(3-Bromophenyl)-1H-[1,2,4]triazole (1.7 g, 7.6 mmol) was coupled to 3-tributylstannyl-7-trifluoromethylimidazo[1,2-a]pyrimidine (3.8 mmol) by the method of Example 32. Purification by chromatography on silica gel eluting with dichloromethane on a gradient of methanol (1-3%), then crystallisation from toluene/isohexane, gave 3-[3-([1,2,4]triazol-1-yl)-phenyl]-7-trifluoromethylimidazo[1,2-a]pyrimidine as an off-white solid: δH (400 MHz, DMSO) 9.43 (1H, d, J 7), 9.41 (1H, s), 8.38 (1H, s), 8.30 (1H, s), 8.26-8.28 (1H, m), 7.97-8.00 (1H, m), 7.76-7.81 (2H, m), 7.56 (1H, d, J 7); m/z (ES+) 331 (M++H).
