Procedure

To a solution of 2-(1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinolin-9-yl)acetic acid (16), (85 mg, 0.229 mmol) in dicloromethane (10 mL) were added Ethyl amine (0.015 mL, 0.229 mmol), EDCI (103 mg, 0.538 mmol), followed by HOBt (72 mg, 0.538 mmol) under argon at 0° C. The reaction mixture was then stirred at room temperature for overnight. The reaction was quenched with water (30 mL). The residue was isolated in a typical aqueous workup and purified by MPLC (medium pressure liquid chromatography) using silica gel column with 5% MeOH:CH2Cl2 to give N-ethyl-2-(1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinolin-9-yl)acetamide (371), (27 mg, 29%).
