Versuchsvorschrift
1.00 M of Borane-THF complex in Tetrahydrofuran (10.0 mL; Acros) was added to 1-(3-Nitro-7,8-dihydro-6H-5-oxa-9-aza-benzocyclohepten-9-yl)-2-pyrrolidin-1-yl-ethanone (0.401 g, 1.31 mmol) in Tetrahydrofuran (10 mL). The mixture was heated at 60° C. under an atmosphere of Nitrogen. overnight. The mixture was quenched with 1N HCl (5 mL) and stirred for 1 h at 60° C. The solution was neutralized by pouring into satd. sodium bicarbonate and extracted with DCM (3×). The extract was dried and conc. in vacuo to give 3-Nitro-9-(2-pyrrolidin-1-yl-ethyl)-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocycloheptene as an oil (270 mg, 70%).
