実験手順

A solution of 4.50 g (12.6 mmols) of ethyl 3-(4-benzyloxy-2-chlorophenyl)-2-azidopropenoate in 100 ml of toluene was refluxed for 3 hours. The reaction mixture was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography to give 3.73 g (89.8%) of ethyl 6-benzyloxy-4-chloro-2-indolecarboxylate.
