실험 절차

A solution of 7-(2-chloro-5-fluorophenyl)-4-methyl-5,6,7,8-tetrahydroquinolin-5-one in ethanol (10 ml) was combined with aminoguanidine hydrochloride (0.041 g), concentrated hydrochloric acid (0.078 ml) and water (0.078 ml), and the mixture was heated under reflux for 4 hours. The solvent was distilled off under reduced pressure, and the residue was combined with water and the aqueous layer was washed with ethyl acetate. The aqueous layer was made alkaline with aqueous sodium hydrogen carbonate and extracted with ethyl acetate. The organic layer was washed successively with water and saturated brine, dried over magnesium sulfate and concentrated under reduced pressure. The residue was dissolved in 1N hydrochloric acid (1 ml) and concentrated. The resultant crystal was recrystallized from ethanol-ethyl acetate to obtain 7-(2-chloro-5-fluorophenyl)-5-guanidinoimino-4-methyl-5,6,7,8-tetrahydroquinoline hydrochloride (Compound G) (0.05 g) as a colorless crystal.
