실험 절차
A solution of 400 mg (1.35 mmol) of tert-butyl 3-(3,5-difluorobenzoyl)azetidine-1-carboxylate in 6 mL of HCl in dioxane (4M) and 2.5 mL of TFA was stirred for 4 h at 50° C. The reaction mixture was concentrated, and the residue was washed with hexanes/ether (1/1) to afford the title compound. Mass Spectrum: m/e=199 (M+1).
