Reaction Steps
A solution of 1.40 g of 1-(4-benzyloxybenzyl)-2-propylthio-5-hydroxymethylimidazole in 15 mL of trifluoroacetic acid was refluxed for 0.25 hour. After cooling, the reaction was poured into water containing an excess of sodium bicarbonate, and the resulting emulsion was extracted with ethyl acetate. The combined organic phases were washed with brine, dried over anhydrous sodium sulfate, filtered, and concentrated. Column chromatography on silica gel (elution: 0-5% methanol/chloroform) afforded 0.28 g of 1-(4-hydroxybenzyl)-2-propylthio-5-hydroxymethylimidazole; NMR (200 MHz, DMSO-d6): δ9.41 (s, 1h); 6.88 (s, 1h); 6.79 (A2B2, 4H); 5.14 (t, 1h); 5.07 (s, 2H); 4.33 (d, 2H); 2.89 (t, 2H); 1.54 (sext., 2H); 0.88 (t, 3H).
