Hydrochloric Acid → HCID 57664984, compound

Participants

Reaction Steps

To a solution of 1-{4-[(ethylamino)carbonyl]phenyl}-5-[(3-fluorophenoxy)methyl]-N-(2-hydroxyethyl)-1H-1,2,3-triazole-4-carboxamide (500 mg) obtained in Example 498 in methylene chloride (10 ml) were added pyridine (0.2 ml) and acetic anhydride (0.17 ml), and the mixture was stirred at room temperature for 10 hr. 1N Hydrochloric acid was added to the reaction mixture, and the mixture was extracted with ethyl acetate and washed with saturated brine. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column (ethyl acetate/hexane=1/2 to 1/1) and recrystallized from ethyl acetate/hexane to give the title compound as a colorless powder (480 mg).
