Procedure

Heat a mixture of 2,4-dichloro-6-(4-fluoro-phenyl)-pyrimidine (6.0 g, 24.7 mmol), 1-(5-bromo-3-methyl-pyridin-2-yl)-3-(R)-methyl-piperazine (7.0 g, 25.9 mmol) and K2CO3 (6.8 g, 49.4 mmol) in DMA at 60° C. for 16 h. Partition the mixture between EtOAc and water, dry (Na2SO4) the organic layer and concentrate under reduced pressure. Purify with flash silica gel column eluting with 15% EtOAc/hexanes. Concentrate under reduced pressure to give the title compound.
