Reaction Steps

Hydrogen chloride gas is bubbled into solution of (3-butyl-2,5-diphenyl-3H-imidazol-4-yl)-acetonitrile (187) (640 mg, 2.03 mmol) in methanol (30 mL) at 0° C. for 10 minutes, followed by stirring for 30 minutes. Water (0.0365 ml, 2.03 mmol) is then added and the reaction refluxed at 80° C. for 2 hours. The methanol is then removed in vacuo, the reaction crude is dissolved in ethyl acetate (100 mL) and the organic layer is washed with saturated sodium bicarbonate (1×100 mL), brine (1×100 mL), and dried over magnesium sulfate. The sample is filtered, concentrated and purified by flash chromatography on SiO2 using an eluent of 2:3 ethyl acetate:hexane to afford (3-butyl-2,5-diphenyl-3H-imidazol-4-yl)-acetic acid methyl ester (188) as a colorless oil.
