Reaction Steps

To a mixture of 7-(2-chlorophenyl)-4-methyl-5,6,7,8-tetrahydroquinolin-5-one-1-oxide (0.23 g) and aminoguanidine hydrochloride (100 mg) were added ethanol (6 ml) and concentrated hydrochloric acid (0.1 ml), and the mixture was refluxed for 3 hours. The reaction solution was cooled to room temperature, and the resulting crystals were filtered and dried to give 7-(2-chlorophenyl)-5-guanidinoimino-4-methyl-5,6,7,8-tetrahydroquinoline-1-oxide hydrochloride (Compound 157) (220 mg) as colorless crystals.
