실험 절차

A solution of [2-(6-fluoropyridin-2-yl)-imidazol-1-yl]acetic acid tert-butyl ester (630 mg; 2.27 mmol) and trifluoroacetic acid (4 mL) in dichloromethane (4 mL) is stirred at room temperature for 5 hr. The reaction mixture is concentrated. The residue is treated with 3M HCl in ethyl acetate (10 mL) and the suspension stirred at room temperature for 1 hr. The precipitate is collected, washed with ethyl acetate, and dried to give 2-Fluoro-6-(1H-imidazol-2-yl)-pyridine acetic acid as a tan solid (581 mg), 1H NMR (d6DMSO) δ 8.35-8.26(m,2H), 7.83(s,1H), 7.76(s,1H), 7.44-7.41(m.1H), 5.40(s,2H). LCMS: 222.1(MH+).
