실험 절차
To a suspension of 3-nitro-6,7,8,9-tetrahydro-5H-benzocyclohepten-5-one (7.0 g) in methanol (70 ml), sodium borohydride (1.29 g) was added portionwise at 21°-30° C. and the whole was stirred for 1 hour. The solution was poured into ice water (210 ml) and the resulting precipitate was collected by filtration, washed with water and dried to give 3-nitro-6,7,8,9-tetrahydro-5H-benzocyclohepten-5-ol (6.81 g).
