Versuchsvorschrift

The compound 4-hydroxymethyl 1-(4-iodophenyl)imidazole I-1 (0.810 g, 2.70 mmol) was dissolved in SOCl2 (6 mL). The solution was stirred at room temperature for 15 min. It was then concentrated in vacuo. The residue was partitioned between EtOAc and 5% aq. NaHCO3. The organic layer was separated, dried over Na2SO4, concentrated in vacuo to give 4-chloromethyl 1-(4-iodophenyl)imidazole 1-3 as a solid (0.780 g). MS 318.9 and 320.9 (M+H, Cl pattern).
