Vorschrift

To a mixture of 7-(2,5-dichlorophenyl)-4-methyl-5,6,7,8-tetrahydrocinnolin-5-one (246 mg) and aminoguanidine hydrochloride (98 mg) were added ethanol (5 ml) and concentrated hydrochloric acid (0.1 ml), and the mixture was stirred at 110° C. (bath temperature) for 1.5 hours. The reaction solution was cooled to room temperature, and the crystals were filtered and dried to give 7-(2,5-dichlorophenyl)-5-guanidinoimino-4-methyl-5,6,7,8-tetrahydrocinnoline hydrochloride (Compound 161) (215 mg) as gray white crystals.
