Hydrochloric Acid → HCID 14014852, compound

Participants

Reaction Steps

Hydrogen chloride was passed into a solution of 100 mg of (2RS, 3S)-3-amino-4-cyclohexyl-2-hydroxybutyric acid hydrochloride in 12 ml of isopropyl alcohol with stirring under ice-cooling, and the mixture was heated under reflux for 2 hours. The reaction mixture was evaporated to dryness under reduced pressure, and the residue was purified by silica gel column chromatography (eluent: chloroform/methanol =15/1 by volume), and the eluate was acidified by adding hydrochloric acid. The mixture was evaporated to dryness under reduced pressure to obtain 108 mg of (2RS, 3S)-3-amino-4-cyclohexyl-2hydroxybutyric acid isopropyl ester hydrochloride as a white powder.
