Reaction Steps

To a stirred suspension of 2-(tert-butyl-dimethyl-silanyl)-4-(1-methoxy-2-phenyl-ethyl)-imidazole-1-sulfonic acid dimethylamide (105 mg) at r.t. in ethanol (3 ml) under an argon atmosphere was added 2 N HCl (3 ml). The mixture was heated to reflux for 3 hours. The mixture was cooled to r.t. and concentrated to leave a light yellow solid which was taken up in H2O and brought to pH 12 by the addition of 4 N NaOH. The product was extracted with CH2Cl2/MeOH 4:1. The combined organics were dried over MgSO4, filtered and concentrated. The crude product was purified by column chromatography (silica gel; gradient: CH2Cl2→CH2Cl2/MeOH 9:1) to give 4-(1-methoxy-2-phenyl-ethyl)-1H-imidazole (38 mg) as white solid. MS (ISP): 203.4 ([M+H]+)
