実験手順

N,N-Diisopropylethylamine (14.5 ml) was added dropwise to a stirred suspension of O-methylhydroxylamine hydrochloride (2.32 g) in isopropyl alcohol (25 ml). After 30 minutes cyclohepta-2,6-dienone (3.0 g) in isopropyl alcohol (5 ml) was added dropwise. After 24 hours N,N-diisopropylethylamine (4.9 ml) was added. After 6 hours the mixture was allowed to stand at room temperature overnight. The mixture was evaporated under reduced pressure, diethyl ether added and the resulting mixture extracted with 2M hydrochloric acid (×3). The combined aqueous fractions were washed with diethyl ether (×3), neutralised with sodium hydroxide and extracted with diethyl ether (×3). The combined extracts were washed with brine, dried (MgSO4) and evaporated under reduced pressure. Kugelrohr distillation gave 8-methoxy-8-azabicyclo[3.2.1]octan-3-one (0.86 g).
