Participants

Reaction Steps

3-[3-(6-Chloro-1H-indol-4-ylmethyl)-2-oxo-2,3-dihydro-benzoimidazol-1-yl]-propionic acid methyl ester (248 mg, 0.64 mmol) is dissolved it tert-butanol (20 mL) at 40° C. The reaction is stirred and pyridiniumtrbromide is added portion wise over 5 minutes. The reaction is stirred for 10 minutes and concentrated in vacuo. The crude material is dissolved in acetic acid (10 mL) and zinc powder (211 mg, 3.2 mmol)is added to the reaction. The reaction is stirred at room temperature for one hour, then the solvent evaporated in vacuo. The residue is taken up in dimethyl sulfoxide and filtered. The crude material is purified by preparative reverse phase LC to give the title compound (34 mg 0.09 mmol, 36%).
