Reaction Steps

A mixture of 6-(2-chlorophenyl)-3-methyl-4,5,6,7-tetrahydrobenzothiophene-4-one (0.07 g), aminoguanidine hydrochloride (0.034 g), concentrated hydrochloric acid (0.063 ml), water (0.063 ml) and ethanol (10 ml) was refluxed for 4 hours. Under reduced pressure, the solvent was evaporated, and the residue was recrystallized from ethanol to give 6-(2-chlorophenyl)-4-guanidinoimino-3-methyl-4,5,6,7-tetrahydrobenzothiophene hydrochloride (Compound 117) (80 mg) as colorless crystals.
