Procedure

To a solution of ethyl 2-[(furan-2-ylmethyl)amino]-5,6,7,8-tetrahydroquinoline-3-carboxylate (600 mg) in ethanol (4 ml)-water (4 ml) was added 8 M aqueous sodium hydroxide solution (1.25 ml), and the mixture was stirred at 80° C. for 10 hr. The reaction mixture was concentrated under reduced pressure to about 1/3 volume, and neutralized with 1 M hydrochloric acid, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the object compound (522 mg).
