Reaction Steps

To a suspension of sodium hydride (0.20 g) in anhydrous toluene (23 ml) was added a hot solution of methyl 3-(indol-4-yl)benzoate (1.16 g) in toluene (5.8 ml). Since a sodium salt did not form, N,N-dimethylformamide (0.5 ml) was introduced. An evolution of gas occurred with the formation of the orange sodium salt of the indole. After being stirred for 20 minutes methyl iodide was added thereto and the mixture was stirred at 60° C. for four hours. Then the sodium iodide was filtered off and washed with toluene. The filtrate was concentrated under reduced pressure and the residue was purified by column chromatography on silica gel eluting with a mixture of hexane and acetone (20:1) to afford methyl 3-(1-methylindol-4-yl)benzoate (0.35 g).
