실험 절차
Potassium hydroxide (4.36, 76 mmol, 1.3 eq.) is suspended in 40 ml of anhydrous DMSO, to the suspension is added a solution 2-phenyl-4-(4-methoxyphenyl)imidazole (15.02, 60 mmol) and bromobutane (8.63 g, 63 mmol, 1.05 eq.) in 80 ml of DMSO at room temperature over 2h, the resulting mixture is stirred over 24h, and then poured into 400 ml of ice-water, extracted with ethyl acetate (100 ml×4), washed,with water and brine, dried over anhydrous sodium sulfate. The solvent is evaporated and the product is purified through flash chromatography to give 16.73 g of 4-({[3-Butyl-5-(4-methoxy-phenyl)-2-phenyl-3H-imidazole. MS (+VE) m/z 307 (M+1).
