실험 절차

(6-(3,5-dimethylisoxazol-4-yl)-2-ethoxy-1H-benzo[d]imidazol-4-yl)(pyridin-2-yl)methanone (50 mg, 0.14 mmol) was dissolved in dry THF (1.4 mL) and cooled to 0° C. Cylobutylmagnesium chloride (0.5 M, 1.1 mL, 0.55 mmol) was added dropwise and the reaction was allowed to stir for 10 mins and then quenched with water. Reaction was extracted three times with EtOAc and combined organic layers were washed once with water, concentrated, and purified by reverse-phase HPLC to give cyclobutyl(6-(3,5-dimethylisoxazol-4-yl)-2-ethoxy-1H-benzo[d]imidazol-4-yl)(pyridin-2-yl)methanol intermediate. The intermediate was taken up in EtOH (1.5 mL) and 4.0 M HCl/dioxane and heated to 65° C. for 2 hours, concentrated and purified by reverse-phase HPLC to afford the desired product as a white powder.
