Reaktionsschritte
A solution of the product from Example 219 (0.3 g) in tetrahydrofuran (2 ml) containing 4-(2-aminoethyl)benzenesulfonamide (0.161 g) and N-ethyldiisopropylamine (0.5 ml) was stirred for 16 hours. The mixture was evaporated to dryness then purified (SiO2, ethyl acetate:dichloromethane 4:6 as eluant) to give the title compound (310 mg).
