Versuchsvorschrift
To a solution of the above aldehyde (1.53 g, 6.11 mmol) in CH2Cl2 (50 mL) at 0° C. was added TFA (5 mL) as described in J. Med. Chem. (1997) 40:2196. Purification by flash column chromatography using EtOAc/hexane (1:1) afforded [1-(toluene-4-sulfonyl)-1H-imidazol-2-yl]-methanol as a white solid (0.55 g, 36%). 1H NMR (CDCl3) δ 2.45 (s, 3H), 3.03 (br s, 1H), 4.84 (s, 2H), 6.99 (d, 1H, J=3.0 Hz), 7.35 (s, 1H), 7.39 (d, 2H, J=3.0 Hz), 7.83 (d, 2H, J=9.0 Hz).
