Dissolve 4-[6-(3-chloro-4-fluoro-phenyl)-2-(4-propyl-piperazin-1-yl)-pyrimidin-4-yl]-piperazine-1-carboxylic acid tert-butyl ester (2.0 g) in dioxane and then add a 4M solution of HCl in dioxane (15 mL). After the formation of precipitate stir the suspension vigorously for 2 h. Collect the solid and wash with ether and then freebase the material by partitioning between 10% NaOH solution and DCM. Separate the organic layer, dry (Na2SO4) and concentrate to give the title compound as an off-white solid.
