실험 절차

2-{5-[2-(tert-Butyldimethylsilanyloxy)-ethyl]-imidazol-1-ylmethyl}-benzonitrile (1.14 g, 3.34 mmol) is dissolved in THF (20 mL) and cooled to −78° C. LHMDS (1M in THF, 5 mL, 5 mmol) is added dropwise. Ten min after the end of addition, acetone (0.295 g, 5.01 mmol) is added. The reaction mixture is stirred at −78° C. for 40 min. It is then quenched with saturated aqueous sodium bicarbonate (10 mL). The mixture is allowed to warm to room temperature, then poured into water. After extraction with ethyl acetate the organic phase is dried over Na2SO4 and concentrated in vacuo to give 2-(1-{5-[2-(tert-butyldimethylsilanyloxy)-ethyl]-imidazol-1-yl}-2-hydroxy-2-methyl-propyl)-benzonitrile; MS (ESI) m/z 400.3 (M+H)
