Procedure
A mixture of 14 g of sodium 2,3,3-trimethyl-3H-indole-5-sulfonate and 14 g 1,3-propanesultone in 100 mL dicholorobenzene was heated at 110° C. for 2 h. After it cooled down, the solvent is decanted. The resulting solid was then dissolved in 100 mL of acetonitrile, and 300 mL of ethyl acetate was added. The resulting sticky solid was again stirred in 300 mL of ethyl acetate to yield 20 g of the product.
