実験手順

To a mixture of 4-methyl-7-(thiophen-3-yl)-1,2,5,6,7,8-hexahydroquinoline-2,5-dione (0.155 g) and aminoguanidine hydrochloride (73 mg) were added 2-ethoxyethanol (2 ml) and 2N hydrochloric acid (0.3 ml), and the mixture was stirred at 125° C. for 13 hours and cooled. Precipitated crystals were filtered, washed with ethanol and dried to give 5-guanidinoimino-4-methyl-7-(thiophen-3-yl)-1,2,5,6,7,8-hexahydroquinolin-2-one hydrochloride (Compound 138) (0.093 g) as colorless crystals.
