To solution of (R)-tert-butyl 4-(tert-butyldimethylsilyloxy)-2-(5-fluoro-2-methoxyphenyl)pyrrolidine-1-carboxylate (1.01 g, 2.37 mmol) in CH2Cl2 (10 mL) at 0° C. was added 4 M HCl in dioxane (5.93 mL, 23.7 mmol). The resulting mixture was warmed to ambient temperature and stirred for 8 hours. The reaction mixture was concentrated under reduced pressure to give the crude material that was triturated with ether. The resulting solids were filtered and dried under reduced pressure to afford (R)-5-(5-fluoro-2-methoxyphenyl)pyrrolidin-3-ol hydrochloride (0.577 g, 2.33 mmol, 98.2% yield). MS (APCI) m/z=212.0 (M+H).
