Reaction Steps

A solution of 1-(4-chlorobenzyl)-1H-indole (2.0 g) in dry ethyl ether (5 ml) kept under stirring and cooled to 0° C. is added drop by drop with a solution of oxalyl chloride (0.85 ml) in dry ethyl ether (2 ml). Afterwards the reaction is left at room temperature for 2 h. The separated solid is recovered by filtration, washed with dry ethyl ether and dried under vacuum at 40° C. to give 2-(1-(4-chlorobenzyl)-1H-indol-3-yl)-2-oxo-acetyl chloride (1.64 g).
