Procedure

Heat a mixture of 4-[4-(5-bromo-3-methyl-pyridin-2-yl)-2-(R)-methyl-piperazin-1-yl]-2-chloro-6-(4-fluoro-phenyl)-pyrimidine (7.7 g, 16.2 mmol), (R)-2-methylpyrrolidine hydrobromide [prepared essentially as described by Nijhuis et. al. (1989) J. Org. Chem. 54(1):209] (3.5 g, 21.1 mmol) and K2CO3 (5.1 g, 37.3 mmol) in DMA at 110° 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 10% EtOAc/hexanes. Concentrate under reduced pressure to give the title compound.
