To a solution of methyl 4-{[((1R,2S)-2-{[(3aR,4R,9bR)-4-phenyl-2,3,3a,4,5,9b-hexahydro-1H-pyrrolo[3,2-c]quinolin-1-yl]carbonyl}cyclohexyl)amino]carbonyl}benzoate (77 mg, 0.14 mmol) in tetrahydrofuran (4 ml) and methanol (1 ml) was added 2N aqueous sodium hydroxide solution (1 ml), and the mixture was stirred at 60° C. for 16 hrs. The reaction mixture was neutralized (pH 7) by adding 3N hydrochloric acid under ice-cooling. The mixture was concentrated under reduced pressure and extracted with a mixed solvent of ethyl acetate-tetrahydrofuran (2:1, v/v). The extract was dried over anhydrous Na2SO4, and the solvent was evaporated under reduced pressure. The obtained solid was washed with isopropyl ether-hexane (1:2, v/v) to give the title compound (51 mg, 68%) as a white solid.
