Reaktionsschritte

To 2-(1-Amino-2-methyl-propyl)-3-benzyl-5,6-dimethyl-3H-pyrimidin-4-one (0.66 g, 2.33 mmol) in DMF (15 mL) was added 2-(4-bromo-3-oxo-butyl)-isoindole-1,3-dione (0.69 g, 2.33 mmol, prepared as described in WO 89/10360) and N,N-diisopropylethylamine (0.301 g, 2.33 mmol). The reaction was stirred for 16 h at room temperature, concentrated under vacuum, dissolved in EtOAc/H2O, washed with water, dried (Na2SO4), and evaporated to give the title compound as a white foam (1.04 g, 89%). MS(ES+) m/e 501 [M+H]+.
