Reaktionsschritte

To 6-(2-benzyloxy-5-cyanophenoxy)-4-chloro-5-nitro-2-methylthiopyrimidine (2.5 g, 5.83 mmol) in 50 mL acetonitrile at 0° C. was added cesium carbonate (2.47 g, 7.58 mmol) followed by benzylamine (0.64 mL) and the reaction mixture was heated at 50° C. for 4 hours. The reaction was filtered, the filtrate evaporated and the residue chromatographed on silica gel (ethyl acetate:hexane) to afford 1.82 g (65%) of 6-(2-benzyloxy-5-cyanophenoxy)-4-(benzyl)amino-5-nitro-2-methylthiopyrimidine, a compound of formula (E).
