실험 절차
A mixture of 4-(3-(4-tert-butylphenyl)-2-oxoimidazolidin-1-yl)benzaldehyde (32 mg, 0.1 mmol), acetic acid (50 μl) and azetidine-3-carboxylic acid (13 mg, 0.13 mmol) in dichloromethane/MeOH (1:1, 5 mL) was stirred at room temperature for 1 hour. Sodium cyanoborohydride (3.5 mg, 0.05 mmol) was added and the reaction mixture was stirred for 6 hour at room temperature. After concentration of solvent under reduced pressure, the resulting residue was dissolved in dimethylsulfoxide, filtered and purified by reverse phase preparative HPLC (Phenomenex reverse phase Luna 5u C18(2) column, 60×21.2 mm ID, mobile phase: A=0.05% TFA in water; B=0.05% TFA in acetonitrile. The flow rate was 10-12 mL/min) to yield the title product 4 mg (10%): 1H NMR (400 MHz, CDOD3) δ 7.72 (d, 2H), 7.51-7.40 (m, 6H), 4.33 (s, 2H), 4.28 (m, 4H), 4.02 (s, 4H), 3.64 (m, 1H), 1.32 (s, 9H). MS (ESI) m/z: Calculated: 407.22; Observed: 408.00 (M++1).
