To a solution [(R)-1-(3-cyano-azetidine-1-carbonyl)-2,2-dimethyl-propyl]-carbamic acid tert-butyl ester (180 mg, 0.49 mmol) in dichloromethane (3 ml) at 0° C. was added trifluoroacetic acid (1.2 ml, 15.6 mmol). The reaction mixture was stirred at room temperature for 2 h then concentrated to afford 1-((R)-2-amino-3,3-dimethyl-butyryl)-azetidine-3-carbonitrile trifluoroacetate as a light yellow oil which was used without further purification.
