Reaction Steps

A solution of 2.05 g of 1-(4-benzyloxybenzyl)-2-propylthio-5-carboethoxyimidazole in 10 mL of tetrahydrofuran was added dropwise to 10 mL of 1M lithium aluminum hydride in THF at 0° such that the reaction temperature remained below 5°. The resulting solution then was stirred at 0° for 1 hour. At this point, the reaction mixture was quenched by sequential dropwise addition of 0.40 mL of water, 0.40 mL of 15% aqueous sodium hydride, and 1.20 mL of water. The resulting suspension was filtered employing diethyl ether, and the filtrate was concentrated to furnish 1.55 g of 1-(4-benzyloxybenzyl)-2-propylthio-5-hydroxymethylimidazole; NMR (200 MHz, CDCl3): δ7.41-7.29 (m, 5H); 7.03-6.86 (m, 5H); 5.22 (s, 2H); 5.01 (s, 2H); 4.45 (s, 2H); 3.01 (t, 2H); 2.32 (bs, 1h); 1.66 (sext., 2H); 0.97 (t, 3H).
