Reaction Steps

5-(3-fluoro-4-methoxy-phenyl)-6,7-dihydro-5H-pyrrolo[1,2-c]imidazole-5-carboxylic acid methyl ester (0.530 g, 1.82 mmol) is dissolved in THF/water (20 mL) (3:2) and to the solution is added LiOH (0.230 g, 9.58 mmol). After 1 h, the solution is brought to pH 4-5 with 1 M HCl and then evaporated to dryness to give 5-(3-fluoro-4-methoxy-phenyl)-6,7-dihydro-5H-pyrrolo[1,2-c]imidazole-5-carboxylic acid that is used without further purification. MS (ESI) m/z 277.2 (M+H).
