Reaction Steps

The title compound was prepared in analogy to the procedure described for Intermediate AW but in the step corresponding to Step AW2, 5-bromo-2-[(4-chloro-3-fluoro-phenyl)-hydroxy-methyl]-1-isopropyl-1H-pyrrole-3-carboxylic acid methyl ester (Step AZ1) and 5-amino-3-chloro-1-methyl-1H-pyridin-2-one (Step E5) were used instead of 5-bromo-2-[(4-chloro-phenyl)-hydroxy-methyl]-1-isopropyl-1H-pyrrole-3-carboxylic acid methyl ester and 2,5-dimethyl-2H-pyrazol-3-ylamine respectively. Moreover, in this step, the procedures described for Steps H3 and H2 using 1-chloro-N,N,2-trimethylpropenylamine and Et3N were used. The title compound (containing some of the corresponding 2-chloro analog) was obtained as a white foam. tR: 1.18 min (HPLC 3); ESI-MS: tR=1.10 min, [M+H]+ 512/514/516 (LC-MS 1); TLC: Rf=0.19 (EtOAc).
