Versuchsvorschrift
To 6-oxabicyclo[3.2.1]oct-3-en-7-one (2.6 g, 21 mmol) in xylenes (50 ml) under nitrogen was added benzylamine (3.42 g, 32 mmol). The mixture was heated under reflux for 16 h, then cooled to room temperature. The heavy white precipitate was collected by filtration, and recrystallized from dichloromethane/hexane to give the amide as a white solid (3.8 g, 78%, m.p. 127-128° C.).
