Lithium hydroxide, monohydrate → HCID 12020408, compound

Participants

Reaction Steps

Lithium hydroxide hydrate, in an amount of 25 mg, dissolved in 5 mL of water was added to 90 mg of (1R,2S,5R,6R)-2-amino-6-fluoro-bicyclo[3.1.0]hex-3-ene-2,6-dicarboxylic acid 2-benzyl ester 6-ethyl ester dissolved in 2 mL of tetrahydrofuran, and the mixture was stirred for 2 hours at room temperature. The solvent was concentrated under reduced pressure. The residue was purified by ion exchange resin (AG 50W-X8 Resin (H type), eluent: water, a 50% aqueous solution of tetrahydrofuran, and a 10% aqueous solution of pyridine), thereby yielding 24 mg of (1R,2S,5R,6R)-2-amino-6-fluoro-bicyclo[3.1.0]hex-3-ene-2,6-dicarboxylic acid.
