Reaction Steps

To a solution of 7-(5-chloro-2-fluorophenyl)-4-methyl-5,6,7,8-tetrahydroquinolin-5-one hydrochloride (0.6 g) and aminoguanidine hydrochloride (0.233 g) in ethanol (10 ml) was added concentrated hydrochloric acid (0.1 ml), and the mixture was stirred at 110° C. (bath temperature) for 2 hours. The reaction solution was cooled to room temperature, and the crystals were filtered and dried to give 7-(5-chloro-2-fluorophenyl)-5-guanidinoimino-4-methyl-5,6,7,8-tetrahydroquinoline hydrochloride (Compound 171) (0.6 g) as colorless crystals.
