Participants

Reaction Steps

A solution of ethyl 1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline-9-carboxylate (13), (4 g, 10 mmol), in EtOH (40 mL) was subjected to saponification reaction using 2N NaOH (40 mL). The residue was isolated in a typical aqueous workup and purified by MPLC (medium pressure liquid chromatography) using silica gel column with 30 to 40% EtOAc:Hexane to give 1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline-9-carboxylic acid (14), (2 g 54%).
