Procedure

A mixture containing 22.5 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), 0.1 mL of acetic acid, 0.1 mL of water, and 0.2 mL of concentrated hydrochloric acid was stirred for 6 hrs approximately under heating at 75° C. (external temperature). The reaction mixture was concentrated under reduced pressure to obtain 24.6 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-carboxylic acid (6f) as a light brown solid.
