To a solution of 1-benzyloxycarbonyl-5-chloro-3-hydroxymethylindole (1.45 g) in dichloromethane (23 ml) was added thionylchloride (0.797 μl) at −78° C. After the mixture was stirred for 1.5 hours at room temperature, the reaction mixture was concentrated under the reduced pressure to give a residue. Hexane was added to the residue. 1-benzyloxycarbonyl-5-chloro-3-chloromethylindole (1.43 g) was obtained as a crystal.
