実験手順

To 2-cyclohexylmethoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-5-ol (14.2 g, 52.0 mmol) in toluene (100 mL) at 0° C. was added DBU (9.4 mL, 62.9 mmol) followed by diphenylphosphoryl azide (13.6 mL, 62.9 mmol). The mixture was allowed to stir for 18 h at rt, diluted with EtOAc, then washed successively with 1 N HCl, and water. The organic layer was dried over MgSO4, filtered, concentrated, and chomatographed over silica gel (5% EtOAc/hexane) to yield a 7:3 mixture of 5-azido-2-cyclohexylmethoxy-6,7,8,9-tetrahydro-5H-benzocycloheptene/3-cyclohexylmethoxy-6,7-dihydro-5H-benzocycloheptene (12.6 g). This mixture was used without further purification in the next reaction.
