To a solution of [(R)-2-(3-cyano-azetidin-1-yl)-1-cyclopropyl-2-oxo-ethyl]-carbamic acid tert-butyl ester (190 mg, 0.69 mmol) in dichloromethane (4 ml) was added trifluoroacetic acid (1.8 ml, 23.4 mmol). The reaction mixture was stirred at room temperature for 2.5 h then concentrated to afford 1-((R)-2-amino-2-cyclopropyl-acetyl)-azetidine-3-carbonitrile trifluoroacetate as a light yellow oil which was used without further purification.
