실험 절차

To a solution of (2S,4S)-2-(4-cyclobutyl-[1,4]diazepane-1-carbonyl)-4-(4-fluoro-phenoxy)-pyrrolidine (102 mg, 0.85 mmol) and Et3N (0.197 mL) in THF (2.82 mL) was added acetyl chloride (60 μL, 0.85 mmol). After 48 h, the mixture was diluted with saturated (satd.) aq. NaHCO3 and extracted with CH2Cl2 (3×). The combined organic layers were dried and evaporated. The residue was purified by FCC, followed by reverse phase HPLC (5-99% CH3CN/20 mM NH4OH) to give the desired product (69 mg, 61%). MS (ESI): mass calcd. for C22H30FN3O3, 403.23; m/z found, 404.3 [M+H]+. 1H NMR (CDCl3): 7.02-6.92 (m, 2H), 6.87-6.77 (m, 2H), 4.92-4.79 (m, 2H), 4.12-3.96 (m, 1H), 3.84-3.47 (m, 5H), 2.92-2.77 (m, 1H), 2.66-2.51 (m, 2H), 2.50-2.41 (m, 2H), 2.39-2.30 (m, 1H), 2.22-2.12 (m, 1H), 2.10 (d, J=2.1 Hz, 3H), 2.07-1.98 (m, 2H), 1.92-1.72 (m, 4H), 1.71-1.54 (m, 2H).
