Reaction Steps
In a 10 ml, three necked flask fitted with a magnetic stirrer, under inert atmosphere, {5-[(2-oxo-4-propylpyrrolidin-1-yl)methyl]-1H-imidazol-1-yl}acetic acid x50 (0.1 g, 0.33 mmol) is dissolved in DMF (1 ml). Triethylamine (0.1 ml, 0.66 mmol), benzylamine (37 μl, 0.33 mmol) and TBTU (0.16 g, 0.33 mmol) are added and the mixture is stirred for 0.5 h at room temperature. An additional amount of benzylamine (0.0165 mmol) is added and stirring is continued overnight. The solvent is evaporated and the residue is purified by chromatography on silicagel (AcOEt/MeOH/NH4OH: 90/9/1 (v/v/v)). The product is treated with a methanolic solution of HCl and the obtained solid is recrystallized from acetonitrile to afford N-benzyl-2-{5-[(2-oxo-4-propylpyrrolidin-1-yl)methyl]-1H-imidazol-1-yl}acetamide 124.
