실험 절차

1.52 g (corresponding to 2.99 mmol) of 2-[4′-(3″-t-butyldimethylsiloxypropoxy)phenyl]-6-iodoimidazo[1,2-a]pyridine was dissolved in 5.0 mL of tetrahydrofuran, and 2.99 mL of a 1.0 mol/L tetrahydrofuran solution of tetrabutylammoniumfluoride was added thereto. After the reaction mixture was stirred at room temperature for 30 minutes, ammonium chloride solution was added followed by the addition of 10 mL of water and 5.0 mL of acetonitrile to filter precipitates. The filtered precipitates were washed with water and acetonitrile in this order, to obtain 1.03 g (corresponding to 2.61 mmol) of 2-[4′-(3″-hydroxypropoxy)phenyl]-6-iodoimidazo[1,2-a]pyridine (FIG. 2-10, Step 5).
