Participants

Reaction Steps

Sodium azide (1.8 g, 27.7 mmol) was added to a (1R,4R,7S)-4-Methyl-8-oxa-3-aza-bicyclo[5.1.0]octane-3-carboxylic acid benzyl ester (2.4 g, 9.2 mmol, Example 1e) and ammonium chloride (1.48 g, 27.7 mmol) in MeOH (16 ml) and H2O (1.6 ml), then was refluxed overnight. The reaction mixture was concentrated in vacuo by rotary evaporation, then was diluted with water (5 ml) and extracted with EtOAc (10 ml). The organic layer was then extracted with water, brine, dried with MgSO4, filtered, concentrated in vacuo by rotary evaporation, and chromatographed (silica gel, 25% EtOAc/hexanes) to yield the title compound (1.76 g, 63%); Liquid chromatgraphy/Electrospray mass spec: M+H+=305.2.
