Reaction Steps

368 mg (corresponding to 0.595 mmol) of 2-[4′-(2″-t-butyldiphenylsiloxyethoxy)phenyl]-6-iodoimidazo[1,2-a]pyridine was dissolved in 1.0 mL of tetrahydrofuran (THF), and 0.70 mL of a 1.0 mol/L tetrahydrofuran solution of tetrabutylammoniumfluoride (TBAF) was added thereto. After the reaction mixture was stirred at room temperature for 2 hours, ammonium chloride solution was added, followed by addition of 5.0 mL of water and 2.0 mL of acetonitrile. Then, precipitates were filtered. The filtered precipitates were washed with water and acetonitrile in this order, to obtain 226 mg (corresponding to 0.595 mmol) of 2-[4′-(2″-hydroxyethoxy)phenyl]-6-iodoimidazo[1,2-a]pyridine (FIG. 2-1, Step 5).
