In a round-bottomed flask, [(R)-1-(4-hydroxymethyl-oxazol-2-yl)-ethyl]-carbamic acid tert-butyl ester (137 mg, 0.51 mmol) was dissolved in dichloromethane (3 ml) and trifluoroacetic acid (1.2 ml, 15.6 mmol) was slowly added. The reaction was stirred at room temperature for 1.5 h then concentrated to afford [2-((R)-1-amino-ethyl)-oxazol-4-yl]-methanol trifluoroacetate as a brown oil which was used without further purification.
