Reaction Steps

8.7 g of oxalyl chloride are added dropwise to a stirring solution, cooled to about -10° C., of 12.0 g of 5,6-dimethoxy-2-methylindole in 250 ml of ether. After addition is completed, the mixture is stirred for 10 minutes, producing a bright orange precipitate of 5,6-dimethoxy-2-methyl-3-indole glyoxylyl chloride which is immediately used for the next step.
