Procedure
To a solution of 5-(2-chloro-ethoxy)-2-methyl-1H-indole-3-carboxylic acid benzyl ester (0.873 mmol, 0.300 g, Example 1, Step A) in 10 mL of 2-butanone was added sodium iodide (8.73 mmol, 1.31 g). The solution was heated at reflux for 48 hours, cooled to room temperature, and concentrated to afford the crude product, 5-(2-iodo-ethoxy)-2-methyl-1H-indole-3-carboxylic acid benzyl ester: MS(APCI+): m/z 436.0 (M+1).
