Procedure

Under a hydrogen atmosphere 77 mg (0.12 mmol) 3-{1-[6-(3-bromo-7,8-dihydro-5H-1,6-naphthyridin-6-carbonyl)-pyrimidin-4-yl]-piperidin-4-yl}-7-methoxy-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one and 40 mg palladium on charcoal (10%) were hydrogenated in 10 mL methanol at 50° C. under 50 psi hydrogen pressure. Then the catalyst was removed by suction filtering and the filtrate was evaporated down i. vac. The residue was purified by preparative HPLC. The product fractions were combined and lyophilised.
