Hydrochloric Acid → HCID 66628602, compound

Participants

Reaction Steps

15 mg of lithium hydroxide monohydrate was added to 131 mg of (1R,2R,3R,5R,6R)-2-amino-3-(3,4-dichlorobenzyloxy)-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid 2-butyl ester 6-ethyl ester dissolved in 2 mL of tetrahydrofuran and 1 mL of water, and the mixture was stirred for 1.5 hours at room temperature. After 2 mL of 1N hydrochloric acid was added thereto, the reaction solution was concentrated under reduced pressure, and the obtained residue was purified by reverse phase chromatography (Wako gel 50C18 (made by Wako Pure Chemical Industries Ltd.) eluent:water to a 40% acetonitrile solution), thereby yielding 37 mg of (1R,2R,3R,5R,6R)-2-amino-3-(3,4-dichlorobenzyloxy)-6-fluorobicyclo[3.1.0]hexane-2,6-dicarboxylic acid 2-butyl ester.
