Versuchsvorschrift
In a 250 ml, three necked flask fitted with a magnetic stirrer, ethyl {5-[(2-oxo-4-propylpyrrolidin-1-yl)methyl]-1H-imidazol-1-yl}acetate hydrochloride x49 (5.19 g, 0.018 mol) is dissolved in 2M HCl (150 ml) and heated at 40° C. for 20 h. The reaction mixture is evaporated to dryness to afford the crude acid x50 (6.19 g) that is used as such in the next step.
