실험 절차

(S)-tert-Butyl 4-(3-(2-fluoro-4-(methylsulfonyl)phenoxy)-2-oxopyrrolidin-1-yl)piperidine-1-carboxylate (1.6 g, 3.5 mmol) was dissolved in CH2Cl2 (20 mL) and 4N HCl in dioxane (˜15 mL) was added and stirred at ambient temperature overnight. The reaction was concentrated to afford (S)-3-(2-fluoro-4-(methylsulfonyl)phenoxy)-1-(piperidin-4-yl)pyrrolidin-2-one hydrochloride (1.5 g, 3.8 mmol, 109% yield) as a white solid. Mass spectrum (apci) m/z=357.2 (M+H).
