Participants

Reaction Steps

In 2 mL of ethyl acetate, 104 mg (0.18 mmol) of (1-{4-[3-(4-chloro-3-(trifluoromethyl)phenyl)ureido]-2-fluorophenyl}-1H-indol-5-yl)carbamic acid tert-butyl ester was dissolved, and 2 mL of a 4N hydrogen chloride ethyl acetate solution was added thereto and the mixture solution was stirred at room temperature for one hour. The reaction solution was concentrated and the obtained product was triturated with ethyl acetate to obtain 80 mg (86%) of 1-[4-(5-aminoindol-1-yl)-3-fluorophenyl]-3-(4-chloro-3-(trifluoromethyl)phenyl)urea hydrochloride (Table 1, Compound No. 17).
