실험 절차
337 mg (1.52 mmol) of tert-butyl 3-amino-3-(fluoromethyl)pyrrolidine-1-carboxylate, 457 mg (1.85 mmol) of {[3-(trifluoromethyl)benzoyl]amino}acetic acid, BOP reagent (817 mg, 1.85 mmol) and 0.64 mL (4.6 mmol) of triethylamine were dissolved in 15 mL of DMF at room temperature. The reaction mixture was stirred at r.t. overnight. Direct chromatography on silica gel (flash chromatography grade) with 50% ethyl acetate-hexane gave 578 mg (1.29 mmol, 84%) of tert-butyl 3-(fluoromethyl)-3-[({[3-(trifluoromethyl)benzoyl]amino}acetyl)amino]pyrrolidine-1-carboxylate: 1H NMR (400 MHz, CDCl3) δ 8.15-8.12 (1H, m), 8.05-7.98 (1H, m), 7.81-7.77 (1H, m), 7.63-7.58 (1H, m), 6.64-6.62 (1H, m), 4.20-4.16 (2H, m), 3.61-3.57 (2H, m), 3.55-3.42 (1H, m), 2.98-2.94 (2H, m), 2.90-2.86 (2H, m), 1.62-1.60 (2H, m), 1.45 (9H, s); MS (m/e): 448 (M+1)+.
