실험 절차
In a 50 ml three necked flask fitted with a magnetic stirrer, under inert atmosphere, a solution of (2-aminophenyl){(2-oxo-4-propyl-pyrrolidin-1-yl)methyl}amine a29 (1 eq, 0.69 mmol, 170 mg), propionaldehyde (1.4 eq, 0.966 mmol, 56 mg, 71 μl), acetic acid (0.3 ml) and dioxane (4 ml) was heated at 65° C. during 40 h. After cooling to room temperature, the solvent was removed under vacuum and the crude product was purified by preparative thin layer chromatography (CH2Cl2/MeOH/NH4OH: 96/3.6/0.4) to give of 1-[(2-propyl)-benzimidazol-1-yl)methyl]-4-propylpyrrolidin-2-one 94 (65 mg, 33%).
