실험 절차

A solution of 351 mg 3-(4-{6-[3-(4-fluorophenyl)-1-trityl-1H-4-pyrazolyl]imidazo[1,2-a]pyridin-3-yl}phenoxy)-propyl azide obtained in Example 15 in 10 mL tetrahydrofuran was stirred at room temperature in a stream of nitrogen, 0.15 mL n-butyl phosphine was added thereto and stirred for 2 hours. Then, 2 mL water was added thereto and further stirred for 4 hours. Ethyl acetate and anhydrous sodium sulfate were added to the reaction solution and stirred. The drying agent was filtered off, the filtrate was concentrated, and the residue was subjected to silica gel column chromatography. By gradual elution with an eluent from hexane:ethyl acetate=1:1 (v/v) to ethyl acetate:methanol 100:1 (v/v), 287 mg of the title compound was obtained as a pale brown amorphous.
