Reaction Steps

To an ice-cooled stirred biphasic solution of 4-[2-(1H-imidazol-1-yl)ethoxy]benzenamine (1.00 g; 4.92 mmol) and sodium bicarbonate (2.07 g; 24.6 mmol) in chloroform (100 mL) and water (50 mL) was added a solution of thiophosgene (452 μL; 5.90 mmol) in chloroform (10 mL) over 5 min. The mixture was stirred at ice-bath temperature for 20 min, and then the aqueous and organic phases were separated and the aqueous phase extracted with chloroform (50 mL). The combined chloroform layers were washed with brine, then dried over magnesium sulfate and concentrated under reduced pressure to give 1-[2-(4-isothiocyanatophenoxy)ethyl]-1H-imidazole (1.41 g) as a yellow oil.
