A solution of 5.86 g (0.05 mol) of indole in 25 ml of DMSO is added to a mixture of 1.32 g of sodium hydroxide (0.055 mol, suspension in mineral oil) in 50 ml of dimethyl sulfoxide. The mixture is heated at 60° C. for 1.3 hours and then allowed to cool, and 17.7 g (0.11 mol) of 4-chlorobenzyl chloride are added dropwise. The solution is heated at 60° C., allowed to stand overnight and then poured with stirring into 200 ml of water. The mixture is extracted repeatedly with a total of 75 ml of CH2Cl2, the organic phase is dried with anhydrous sodium sulfate and filtered and the filtrate is concentrated under reduced pressure.
