Reaction Steps

Dissolve 4-chloro-6-(4-fluorophenyl)-2-(2,5-dimethyl-1H-pyrrol-1-yl)pyrimidine (60.4 mg, 0.2 mmoles) and (R)-1-(3-chloro-pyridin-2-yl)-3-methyl-piperazine (42.4 mg, 0.2 mmoles) in DMA (2.0 mL) under nitrogen atmosphere. Add anhydrous powdered K2CO3 (0.4 mmoles) to this mixture and heat at 130° C. for 24 hours. Cool, dilute with water (5 mL), extract with EtOAc (3×2 mL) and dry over MgSO4. Filter and concentrate under vacuum to afford crude product and purify by flash column chromatography using 10% EtOAc/hexane to afford the title product as white amorphous solid.
