Procedure

To a solution of 4-(5-dimethylamino-6-trifluoromethylindol-1-yl)benzoic acid ethyl ester (0.054 g) in N,N-dimethylformamide (2 mL) was added phosphoryl chloride (0.026 g) under ice cooling, and this mixture was stirred at room temperature for 16 hours. To this mixture was added 2 mol/L aqueous sodium hydroxide solution (5 mL), and this resulting mixture was stirred at 50° C. for 30 minutes. After cooling to ambient temperature, 1 mol/L hydrochloric acid (10 mL) was added to this mixture, and the precipitated solid was collected by filtration. This solid was washed with water and n-hexane, dried under reduced pressure at 50° C. to give the title compound (0.026 g).
