A solution of {(S)-1-[(5-ethyl-1,2,4-oxadiazol-3-yl)-hydroxy-methyl]-propyl}-carbamic acid tert-butyl ester (214 mg, 0.751 mmol) in methylene chloride (5 mL) was treated with trifluoroacetic acid (0.578 mL, 7.504 mmol) and stirred at room temperature for 3 hours. Solvent evaporated under reduced pressure to give (S)-2-amino-1-(5-ethyl-1,2,4-oxadiazol-3-yl)-butan-1-ol trifluoroacetate, a mixture of diastereoisomers, (224 mg) as a brown oil.
