実験手順
A mixture of methyl N-[[2-chloro-5-(1H-1,2,3-triazol-5-yl)phenyl]methyl]carbamate (i.e. the product of Step E, Example 9) (0.53 g, 2.0 mmol), 1-chloro-4-iodobenzene (0.57 g, 2.4 mmol), iron(III) acetylacetonate (0.21 g, 0.6 mmol), copper(II) oxide (0.016 g, 0.2 mmol) and cesium carbonate (1.29 g, 4.0 mmol) in N,N-dimethylformamide (4 mL) was heated at 110° C. for 14 h and then concentrated under reduced pressure. The resulting residue was suspended in ethanol and then concentrated onto silica gel (2 g). The silica gel mixture was purified by flash column chromatography using a Supelco (division of Sigma-Aldrich Co., 595 North Harrison Road, Bellefonte, Pa. 16823, U.S.A.) tube prepacked with 10 g of silica gel (50 μm particle diameter, 70 Å pore size) and 3:1 hexanes-ethyl acetate as eluant to provide methyl N-[[2-chloro-5-[2-(4-chlorophenyl)-2H-1,2,3-triazol-4-yl]phenyl]methyl]carbamate, a compound of the present invention, as a beige solid (0.105 g)
