実験手順
2nd method: A homogenized mixture of (1R,6R)-2-oxa-5,8-diazabicyclo[4.3.0]nonane dihydrobromide and 620 mg (11 mmol) of powdered potassium hydroxide is distilled dry in a bulb tube apparatus at 0.2 mbar and increasing oven temperature to 250° C. 490 mg (76.6% of theory) of (1R,6R)-2-oxa-5,8-diazabicyclo[4.3.0]nonane are obtained as a viscous oil, which slowly crystallizes.
