Procedure
[1-(Benzooxazol-2-yl-hydroxy-methyl)-propyl]-carbamic acid tert-butyl ester (275 mg, 0.89 mmol) and MeCl2 (5 ml) were mixed and TFA (1 ml) was added at room temperature. After stirring for 1 hour, the solvent and excess TFA were removed under vacuum to produce 260 mg of 2-amino-1-benzooxazol-2-yl-butan-1-one TFA salt.
Workup
- customthe solvent and excess TFA were removed under vacuum
