Procedure
A suspension of 1-{6-[4-(4-benzyl-piperazin-1-yl)-phenylamino]-pyrimidin-4-yl}-3-(2,6-dichloro-3,5-dimethoxy-6-methyl-phenyl)-1-methyl-urea (100 mg, 0.161 mmol) (Example 13), palladium on carbon (30 mg), MeOH (6 mL), and HCl (37%, 16 μL) is stirred for 5 days at RT, under a hydrogen atmosphere. The reaction mixture is filtered and concentrated. Purification of the residue by silica gel column chromatography (DCM/2N NH3 in MeOH, 95:5) affords the title compound as a beige solid: ESI-MS: 532.0/534.0 [MH]+; tR=3.39 min (purity: 100%, system 1).
