Procedure
A mixture of 5-bromo-2-[(3-chloro-4-fluoro-phenylamino)-(4-chloro-phenyl)-methyl]-1-isopropyl-1H-pyrrole-3-carboxylic acid (Step D1) (1.483 mmol), HATU (1.632 mmol) and NMM (4.45 mmol) in dioxane (75 mL) was heated at 80° C. for 17 h. After cooling to rt, the reaction mixture was diluted with EtOAc and washed with a saturated aqueous solution of NaHCO3. The aqueous phase was extracted with EtOAc (2×). The combined organic phases were washed with brine, dried (Na2SO4), filtered and concentrated. The residue was purified using a RediSep® silica gel column to afford the title compound as a light-yellow solid. tR: 5.31 min (HPLC 2); ESI-MS: tR=1.40 min, [M+H]+481/483/485 (LC-MS 1); TLC: Rf=0.27 (1:3 EtOAc/hexanes).
