실험 절차

To a solution of 7-(2-fluoro-4-nitrophenoxy)-2-(1H-imidazol-4-yl)thieno[3,2-b]pyridine (93) (WO 2006010264) (300 mg, 0.84 mmol) in dry DMF (3 ml) at 0° C. was added NaH (40 mg, 60% dispersion in oil, 1.0 mmol). The mixture was allowed to warm to room temperature over 0.5 h then re-cooled to 0° C. MOMCl (74 mg, 1.1 eq, 0.92 mmol) was added and mixture was allowed to warm to room temperature over 20 hours, concentrated and partitioned between EtOAc and water. The EtOAc phase was dried over anhydrous sodium sulfate, filtered, concentrated and purified by column chromatography (100% hexane to 100% acetone) to afford the title compound 94 (126 mg, 36% yield). MS (m/z): 401.0 (M+H).
