Conditions

Temperature: 60 °C

Procedure

23 μL of thionyl chloride was added to 30 mg of (1R,2R,3R,5R,6R)-2-amino-3-(3,4-dichlorobenzyloxy)-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid suspended in 0.3 mL of 4-fluorobenzyl alcohol at room temperature, and the mixture was stirred for 3 days at 60° C. After standing to cool, the reaction solution was purified by reverse phase chromatography (Wako gel 50C18 (made by Wako Pure Chemical Industries Ltd.) eluent:water, a 70% aqueous solution of acetonitrile), thereby yielding 5 mg of (1R,2R,3R,5R,6R)-2-amino-3-(3,4-dichlorobenzyloxy)-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid 6-(4-fluorobenzyl)ester.
