Lithium Hydroxide → N-(2,2,2-Trifluoro-1-phenylethyl)-L-leucine

Participants

Reaction Steps

To a room temperature solution of methyl N-(2,2,2-trifluoro-1-phenylethyl)-L-leucinate (150 mg, 0.50 mmol) in 2:1 THF/MeOH was added 1M LiOH. The mixture was stirred overnight and concentrated. The residue was partitioned between ethyl acetate and pH 3.5 phosphate buffer. The organic phase was washed with brine, dried over MgSO4 and concentrated to give N-(2,2,2-trifluoro-1-phenylethyl)-L-leucine.
