実験手順
The compound of Formula (IX) was reacted with trifluoroacetic acid in a suitable solvent such as dichloromethane to provide trifluoroacetic acid and sodium salt of 6-sulfooxy-2-(amino methyl)-7-oxo-1,6-diazabicyclo[3.2.1]octane (X). This trifluoroacetic acid and sodium salt (X) was further treated with water isopropyl alcohol mixture to obtain zwitterion form, (2S, 5R)-6-sulfooxy-2-(aminomethyl)-7-oxo-1,6-diaza-bicyclo[3.2.1]octane (XI).
