HCID 115472341-(1-{3-[2-Chloro-4-(2,4-difluoro-phenylamino)-benzoyl]-4-methyl-phenyl}-1H-[1,2,3]triazol-4-yl)-ethanone

Procedure

The reaction was carried out similarly as described in the preparation of compound 116, using compound 434 (0.125 mmol) and but-3-yn-2-one (0.125 mmol). The crude product was purified by continuous gradient flash chromatography using EtOAc/petroleum ether (40-60) 0:100 to 50:50 as the eluent to afford the title compound.
