실험 절차

To a solution of 7-(2-chloro-5-fluorophenyl)-4-methyl-5,6,7,8-tetrahydroquinolin-5-one in ethanol (10 ml) were added aminoguanidine hydrochloride (0.041 g), concentrated hydrochloric acid (0.078 ml) and water (0.078 ml), and the mixture was refluxed for 4 hours. Under reduced pressure, the solvent was evaporated, and to the residue was added water. The aqueous layer was washed with ethyl acetate, and to the aqueous layer was added sodium hydrogen carbonate solution to make it alkaline. The solution was extracted with ethyl acetate, and the organic layer was washed with water and saturated brine, dried with magnesium sulfate, and concentrated under reduced pressure. The residue was dissolved in 1N hydrochloric acid (1 ml) and concentrated to give crystals, which were recrystallized from ethanol-ethyl acetate to give 7-(2-chloro-5-fluorophenyl)-5-guanidinoimino-4-methyl-5,6,7,8-tetrahydroquinoline hydrochloride (Compound 170) (0.05 g) as colorless crystals.
