Reaction Conditions:

with ethylmagnesium bromide in diethyl ether;dichloromethane at 20; for 0.333333 h;

Steps:

4.1. 4-Iodo-1-methyl-1H-imidazole (15)
EtMgBr (3.0 M solution in ether, 11.00 mL, 32.9 mmol) wasadded to a solution of 14 (10.00 g, 29.9 mmol) in dry CH₂Cl₂(150 mL) at rt. over 15 min. The resulting mixture was stirredfor 20 min and water (20 mL) was added to the reaction mixtureafter running a TLC experiment to confirm all the starting materialis consumed. Then, the layers were separated. The aqueous layerwas extracted with CH₂Cl₂ (3 50 mL) and the combined organiclayers were dried (Na₂SO₄) and concentrated to isolate 15 as paleyellow oil (5.86 g, 94%).
