Procedure
Heat a mixture of methanesulfonic acid 5-chloro-6-{4-[6-(4-fluoro-phenyl)-2-(2-methyl-pyrrolidin-1-yl)-pyrimidin-4-yl]-piperazin-1-yl}-pyridin-3-ylmethyl ester with an excess of dimethylamine (1M in THF) in a sealed tube at 80° C. for 2 h. Concentrate under reduced pressure then partition between EtOAc and 10% NaOH solution. Dry the organic layer (Na2SO4) and concentrate under reduced pressure. Purify the resulting residue using flash chromatography (10:90:1/MeOH:DCM:NH4OH eluent) to give the title compound.
