Reaction Steps

The title compound was prepared in analogy to the procedure described for Intermediate AX but in the step corresponding to Step AX1, 5-bromo-2-[(4-chloro-phenyl)-hydroxy-methyl]-1-isopropyl-1H-pyrrole-3-carboxylic acid methyl ester (step D3) and 3-amino-5-chloro-1-(4-methoxy-benzyl)-1H-pyridin-2-one (Step AH1) were used instead of 5-bromo-2-[(4-cyano-phenyl)-hydroxy-methyl]-1-isopropyl-1H-pyrrole-3-carboxylic acid methyl ester and 2,5-dimethyl-2H-pyrazol-3-ylamine respectively. The title compound was obtained as a white solid. tR: 1.38 min (HPLC 3); ESI-MS: tR=1.35 min, [M+H]+ 600/602/604 (LC-MS 1); TLC: Rf=0.46 (1:1 EtOAc/heptanes).
