Procedure
A mixture of 500 mg (1.68 mmol) of the indolecarboxylic acid from Step 4 and 20 ml of thionyl chloride was heated for 3 at 70° C. The excess of thionyl chloride was removed under reduced pressure and the remaining crude acid chloride was dissolved in 30 ml of dry dichloromethane. This solution was used in the next step.
