Sodium Bicarbonate → 2-Chloro-4-(3-chloro-4-fluoro-phenyl)-6-[4-(3-trifluoromethylpyridin-2-yl)-piperazin-1-yl]-pyrimidine

Participants

Reaction Steps

Combine 2,4-dichloro-6-(3-chloro-4-fluoro-phenyl)-pyrimidine (1.6 g, 5.75 mmol), sodium bicarbonate (1.28 g, 15 mmol), MeOH (100 mL) and cool over ice. Drip in a mixture of 1-(3-trifluoromethyl-pyridin-2-yl)-piperazine (1.33 g, 5.75 mmol) in MeOH (50 mL), and let the reaction stir for 16 hours at room temperature. Evaporate the mixture and purify directly using 10:1 hexanes/EtOAc, obtaining 2-chloro-4-(3-chloro-4-fluoro-phenyl)-6-[4-(3-trifluoromethyl-pyridin-2-yl)-piperazin-1-yl]-pyrimidine as a white solid.
