To a solution of 56 mg of the isopropyl hexanoate compound in 3ml of methanol were added 0.2 ml of a 2N-hydrochloric acid and 20 mg of a 10% of palladium charcoal, and the mixture was hydrogenated under a hydrogen atmosphere. After filtration of the catalyst, the filtrate was evaporated under reduced pressure to obtain 42 mg of isopropyl (2RS, 3S)-3-(L-alanyl)amino-2-hydroxy-5-methylhexanoate hydrochloride as a colorless viscous oil.
