Versuchsvorschrift

To a mixture of tert-butyl [2-({3-[(2,5-dichloropyrimidin-4-yl)amino]phenyl}ethynyl)pyridin-4-yl]carbamate (740 mg, 1.6 mmol) in methanol (15 mL) and tetrahydrofuran (15 mL) was added 10% palladium on carbon (148 mg, 0.139 mmol). The resultant mixture was hydrogenated at 55 psi for 20 hours. The crude mixture was filtered and concentrated to give the desired product as a light yellow solid (0.65 g, 87%). LCMS for C22H24Cl2N5O2 (M+H)+: m/z=460.0, 462.0.
