Procedure

A solution of N-benzyl-N-(6,7,8,9-tetrahydro-2-hydroxy-5H-benzocyclohepten-6-yl)-tert-butoxycarbonylamine (166 mg) and N-chlorosuccinimide (66.4 mg) in 1,4-dioxane (2 ml) was refluxed for 28 hours, cooled to room temperature, and partitioned between ethyl acetate and brine. The organic layer was separated, washed with brine, dried over sodium sulfate, and evaporated in vacuo. The residue was chromatographed (toluene-ethyl acetate) over silica gel (3.6 g) to afford N-benzyl-N-(3-chloro-6,7,8,9-tetrahydro-2-hydroxy-5H-benzocyclohepten-6-yl)-tert-butoxycarbonylamine (139 mg) as a colorless gum.
