실험 절차

(S)-3-[3-(5-Bromo-2-oxo-2,3-dihydro-benzothiazol-7-ylmethyl)-2-oxo-2,3-dihydro-benzimidazol-1-yl]-hexanoic acid ethyl ester (33 mg, 0.06 mmol) is dissolved in dioxane (3 mL) and then LiOH (8 mg, 0.3 mmol) in water (3 mL) is added to the reaction. The reaction is stirred for 1 hour then acidified with 4N HCl and the solvents evaporated in vacuo. The resulting crude solid is purified on reverse phase LC/MS to give 10 mg (32%) of the title compound as a white solid. LCMS (ESMS): m/z 491.8 (M+H+).
