Procedure
To a solution 1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinolin-9-amine (Intermediate 4), (100 mg, 0.294 mmol) in dichloromethane (15 mL) was added propyl isothiocyanate (0.038 mL, 0.323 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-propylthiourea (255) (64 mg 49%). 1H NMR (300 MHz, CDCl3) ppm 7.08-7.34 (m, 10H) 6.39 (s, 2H) 4.11 (t, J=6 Hz, 2H) 3.32-3.46 (m, 2H) 3.16-3.23 (m, 4H) 2.25-2.30 (m, 2H) 2.13-2.17 (m, 2H) 1.32-1.39 (m, 2H, 0.73 (t, J=6 Hz, 3H)
