To a solution of [(R)-2-(3-cyanoazetidin-1-yl)-1-methyl-2-oxo-ethyl]-carbamic acid tert-butyl ester (860 mg, 3.4 mmol) in CH2Cl2 (20 mL) was added trifluoroacetic acid (4.0 mL). The reaction mixture was stirred at room temperature for 2 h then concentrated to afford 1-((R)-2-amino-propionyl)-azetidine-3-carbonitrile trifluoroacetate as a pale yellow oil which was used without further purification.
