Versuchsvorschrift

To a solution 1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinolin-9-amine (Intermediate 4), (102 mg, 0.30 mmol) in dichloromethane (15 mL) was added ethyl isocyanate (0.026 mL, 0.33 mmol), mmol) under argon at 0° C. The reaction mixture was then stirred at room temperature for overnight. The solvent was removed under reduced pressure and purified by MPLC (medium pressure liquid chromatography) using silica gel column with 15 to 20% EtOAc:Hexane to get 1-(1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinolin-9-yl)-3-ethylurea (484) (120 mg 97%). 1H NMR (300 MHz, CDCl3) δ ppm 0.91 (t, J=7.18 Hz, 3H) 2.05-2.20 (m, 2H) 2.21-2.39 (m, 2H) 2.96-3.28 (m, 6H) 4.07-4.19 (m, 2H) 4.35 (br. s., 1H) 5.58 (s, 1H) 6.43 (s, 2H) 7.06-7.36 (m, 10H)
