Vorschrift

To a mixture of 7-(2-chlorophenyl)-4-methyl-5,6,7,8-tetrahydrocinnolin-5-one (0.218 g) and aminoguanidine hydrochloride (94 mg) were added ethanol (5 ml) and concentrated hydrochloric acid (0.1 ml), and the mixture was refluxed for 1.5 hours and cooled. Precipitated crystals were filtered, washed with ethanol and dried to give 7-(2-chlorophenyl)-5-guanidinoimino-4-methyl-5,6,7,8-tetrahydrocinnoline hydrochloride (Compound 129) (0.255 g) as crystals.
