実験手順

To a dimethyl sulfoxide (1.2 mL) solution containing 303.0 mg of (1R,2S,3R,5R,6R)-2-amino-2-cyano-3-[(3,4-dichloro benzyl)oxy]-6-fluoro bicyclo[3.1.0]hexane-6-carboxamide (6a), 35.5 mg of potassium carbonate was added under cooling in water bath (13° C. approximately). Subsequently, 0.2 mL of 30 wt % hydrogen peroxide was added thereto and stirred for 30 min. After stirring for 67.5 hrs at room temperature, 3 mL of water was added to the reaction solution and the precipitated solids were filtered and washed with 1.2 mL of water. The resulting solids were dried under reduced pressure at room temperature to obtain 313.2 mg of (1R, 2R,3R,5R,6R)-2-amino-3-[(3,4-dichloro benzyl)oxy]-6-fluoro bicyclo[3.1.0]hexane-2,6-dicarboxamide (7a) as a colorless solid.
