Participants

Reaction Steps

To a solution of N-cyclopropyl-1-{4-[(ethylamino)carbonyl]phenyl}-5-(hydroxymethyl)-1H-1,2,3-triazole-4-carboxamide (200 mg) obtained in Example 112 in THF (4 ml) were added 3-fluorophenol (68 mg), tributylphosphine (182 μM) and ADDP (184 mg), and the mixture was stirred at room temperature for 6 hr. Water 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=1/1 to 2/1) and recrystallized from ethyl acetate/hexane to give the title compound as a colorless powder (180 mg).
