Procedure

A solution of [5-(3,4-dichloro-benzenesulfonyl)-10-methoxy-5,6-dihydro-phenanthridin-6-yl]-acetic acid (Example 17/d) (0.163 g, 0.34 mmol), triethylamine (0.3 mL, 2.1 mmol) and O-benzotriazol-1-yl-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HBTU) (0.152 g, 0.4 mmol) in dry dimethyl formamide (10 mL) was stirred at room temperature for five minutes before trans-4-(2-pyrrolidin-1-yl-ethyl)-cyclohexylamine dihydrochloride (Reference Example 4) (0.09 g, 0.34 mmol) was added. The pH of the reaction mixture was adjusted to 8 by addition of triethylamine, the so obtained mixture was stirred at room temperature overnight, then concentrated in vacuo. The residue was treated with saturated sodium hydrogencarbonate solution (30 mL), the precipitated crystals were filtered off, washed with water and dried. The crude product was purified by column chromatography using Kieselgel 60 (0.040-0.063 mm) (Merck) as adsorbent, and chloroform:methanol:NH4OH=9:1:0.1 as eluent. The product was crystallized with diethyl ether to yield 0.135 g (60%) of the title compound. MS (EI) 657.2 (MH+).
