Reaction Steps

In 10 mL of methanol, 12 mg (0.025 mmol) of 1-{4-[3-(4-chloro-3-(trifluoromethyl)phenyl)ureido]phenyl}-N-hydroxy-1H-indole-5-carboxamidine was dissolved and the solution was subjected to hydrogenation catalytic reduction on 10% palladium carbon in a hydrogen atmosphere at room temperature for 14 hours. After removal of the palladium carbon by a membrane filter, the filtrate was concentrated under reduced pressure, and the obtained product was triturated from diethyl ether to obtain 3 mg (25%) of 1-{4-[3-(3-(trifluoromethyl)phenyl)-ureido]phenyl}-1H-indole-5-carboxamidine (Table 1, Compound No. 25).
