Reaction Steps

A 4 M solution of hydrochloric acid in dioxane (0.22 mL, 0.89 mmol) was added to a solution of (4-{6-Amino-5-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-pyridin-3-yl}-imidazol-1-yl)-acetic acid tert-butyl ester (86 mg, 0.18 mmol) in dichloromethane (2 mL). After stirring for two days the reaction was concentrated by rotary evaporation and the residue was dissolved in a minimum amount of methanol. This solution was added dropwise to ether and the resulting mixture allowed to stand overnight. The mixture was filtered and the precipitate was washed with ether and air dried to give (4-{6-Amino-5-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-pyridin-3-yl}-imidazol-1-yl)-acetic acid (83 mg, 93%).
