Методика

TFA (0.27 mL, 0.414 g, 3.63 mmol) was added to a solution of (4R)-tert-butyl 4-((tert-butyldimethylsilyl)oxy)-2-(2,5-difluorophenyl)pyrrolidine-1-carboxylate (0.5 g, 1.21 mmol) in DCM (10 mL) at 0° C. and stirring was continued at 28° C. for 2 hr. Reaction mixture was concentrated under reduced pressure to afford (4R)-4-((tert-butyldimethylsilyl)oxy)-2-(2,5-difluorophenyl)pyrrolidine hydrochloride (Int-57).
