| Product | [2-Chloro-4-(2,4-difluoro-phenylamino)-phenyl]-{5-[4-(2-hydroxy-ethyl)-[1,2,3]triazol-1-yl]-2-methyl-phenyl}-methanone | HCID 11712482 | — |
Reaction Steps
The reaction was carried out similarly as described in the preparation of compound 110, using compound 434 (6.87 mmol) and 3-butyne-1-ol (8.24 mmol). The crude product was purified by continuous gradient flash chromatography using EtOAc/petroleum ether (40-60) 50:50 to 100:0 as the eluent to afford the title compound as yellow foam.
