Procedure

To a solution of 1H-indole-5-carboxylic acid benzyl ester (3.5 g) in N,N-dimethylformamide (30 mL) was added phosphoryl chloride (2.6 g) under ice cooling and this mixture was stirred at room temperature for 2 hours. To this reaction mixture was added 2 mol/L aqueous sodium hydroxide solution until the pH became 6 and this mixture was stirred at 70° C. for 30 minutes. After cooling to ambient temperature, the precipitated solid was collected by filtration, and washed with water and methanol, dried to give the title compound (3.9 g).
