Participants

Reaction Steps

To a solution (1S,7S)-1,7-dimethyl-9-amino-1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline (9), (110 mg, 0.30 mmol) in dichloromethane (15 mL) was added ethyl isocyanate (0.026 mL, 0.328 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) using silica gel column with 15 to 20% EtOAc:Hexane to get 1-((1S,7S)-1,7-dimethyl-1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinolin-9-yl)-3-ethylurea (249), (96 mg 73%). 1H NMR (300 MHz, Acetone-d6) δ ppm 1.00 (t, J=7.18 Hz, 3H) 1.71 (s, 6H) 1.91-2.02 (m, 2H) 2.15-2.31 (m, 2H) 2.75-2.87 (m, 2H) 2.90-3.03 (m, 2H) 3.03-3.16 (m, 2H) 6.98 (s, 2H) 7.09-7.31 (m, 10H)
