A solution (500 μl; 70 μmol) of 1-{4-[(ethylamino)carbonyl]-2-hydroxyphenyl}-N-cyclopropyl-1H-1,2,3-triazole-4-carboxamide (0.14M) in DMF, and a solution (500 μl; 105 μmol) of (1-bromoethyl)benzene (0.21M) in DMF, and a powder of potassium carbonate (30 mg) were mixed at room temperature, and the mixture was stirred for 16 hr. Water (2 ml) was added to the reaction mixture, and the mixture was extracted with dichloromethane (3 ml). The solvent was evaporated under reduced pressure, and the residue was dissolved in DMSO (1 ml) and purified by preparative HPLC (Gilson, Inc., high-throughput purification system, column: YMC CombiPrep ODS-A S-5 μm, 50×20 mm, solvent: solution A; 0.1% formic acid aqueous solution, solution B; 0.1% formic acid acetonitrile solution, gradient cycle: 0 min (solution A/solution B=95/5), 1.00 min (solution A/solution B=95/5), 5.20 min (solution A/solution B=5/95), 6.40 min (solution A/solution B=5/95), 6.50 min (solution A/solution B=95/5), 6.60 min (solution A/solution B=95/5), flow rate: 25 ml/min, detection method: UV 220 nm) to give the title compound (9.8 mg) (LC/MS purity 100%, ESI+:420 [M+H]+).
