Procedure

Heat a mixture of 4-chloro-6-(4-fluoro-phenyl)-2-(2-methyl-pyrrolidin-1-yl)-pyrimidine (1.30 g, 4.44 mmol), 1-(5-bromo-3-methyl-pyridin-2-yl)-3-(R)-methyl-piperazine (1.2 g, 4.44 mmol), and NaHCO3 (0.71 g, 8.46 mmol) in EtOH at 50° C. for 20 h. Concentrate under reduced pressure and partition between EtOAc and brine. Dry the organic layer (Na2SO4) and concentrate under reduced pressure. Purify the residue by flash column chromatography eluting with EtOAc-hexanes (1:4) to afford the title compound as a white solid.
