3-Bromo-7-(trifluoromethyl)imidazo[1,2-a]pyrimidine → HCID 10134101, compound

Participants

Reaction Steps

4-Fluoro-3-(5-fluoropyridin-2-yl)phenylboronic acid was coupled with 3-bromo-7-trifluoromethylimidazo[1,2-α]pyrimidine by the method of Example 1. Purification by chromatography on silica gel eluting with dichloromethane containing 3.5% methanol, then crystallisation from hot toluene/isohexane and further crystallisation from hot methanol, gave 3-[4-fluoro-3-(5-fluoropyridin-2-yl)phenyl]-7-trifluoromethylimidazo[1,2-α]pyrimidine: δH (400 MHz, DMSO) 9.28 (1H, d, J 7), 8.76 (1H, d, J 3), 8.30 (1H, s), 8.20 (1H, dd, J 7 and 2), 7.88 (3H, m), 7.62 (1H, dd, J 11 and 9), 7.53 (1H, d, J 7).
