Trifluoroacetic acid → 1-((R)-2-amino-propionyl)-azetidine-3-carbonitrile trifluoroacetate

Participants

Reaction Steps

[(R)-2-(3-cyanoazetidin-1-yl)-1-methyl-2-oxo-ethyl]-carbamic acid tert-butyl ester (47 mg, 0.185 mmol) was dissolved in dichloromethane (1 ml) and cooled in an ice bath. Trifluoroacetic acid (0.5 ml) was slowly added and the reaction was stirred at room temperature for 2 h then evaporated and dried under high vacuum to afford 1-((R)-2-amino-propionyl)-azetidine-3-carbonitrile trifluoroacetate which was used without further purification.
