The flask was evacuated and filled up with H2 (contained in a balloon) for five times, then the reaction mixture was stirred under H2 for 20 h. The catalyst was filtered off through a pad of celite washing thoroughly with EtOH, MeOH, CH2Cl2, and acetonitrile (almost one liter of the mixture of solvents was used to ensure the complete solubilization of the product). The solvent was evaporated under reduced pressure and the residue purified by reverse phase chromatography (Buffer A: 0.1% TFA in H2O, Buffer B: 0.1% TFA in CH3CN; Column: Waters, C18, 47×300 mm; gradient: 1.1%, 10%-60% B in 45 min). The free base thus obtained was lyophilized from a 1:1 mixture of acetonitrile and 1N HCl, obtaining the desired 3-[2-morpholin-4-yl-6-(3-pyridylamino)pyrimidin-4-yl]phenol as the bis HCl salt. The spectral data are the following:
