Reaction Steps

Under nitrogen, a suspension of N-benzyl-N-(3-hydroxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)-tert-butoxycarbonylamine (300 mg) and N-chlorosuccinamide (110 mg) in 1,4-dioxane (5 ml) was stirred at 100° C. for 9 hours. The resulting mixture was poured into saturated aqueous sodium hydrogencarbonate and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and evaporated in vacuo. The residue was purified by column chromatography on silica gel (toluene:ethyl acetate=50:1 to 10:1) to give N-benzyl-N-(2-chloro-3-hydroxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)-tert-butoxycarbonylamine (152 mg).
