実験手順
To a mixture of 6-(4-fluorophenyl)-3-trifluoromethyl-4,5,6,7-tetrahydrobenzofuran-4-one (0.25 g) and aminoguanidine hydrochloride (93 mg) were ethanol (20 ml) and 6N hydrochloric acid (0.072 ml), and the mixture was stirred at 90° C. for 4 hours and cooled. The reaction solution was concentrated under reduced pressure, and the residue was washed with ethanol, ethyl acetate and isopropylether, and dried to give (E)-6-(4-fluorophenyl)-4-guanidinoimino-3-trifluoromethyl-4,5,6,7-tetrahydrobenzofuran hydrochloride (Compound 51) (0.20 g).
