5-Amino-3-chloro-1-methyl-1,2-dihydropyridin-2-one → 2-bromo-5-[(5-chloro-1-methyl-6-oxo-1,6-dihydro-pyridin-3-ylamino)-(4-chloro-phenyl)-methyl]-1-isopropyl-1H-pyrrole-3,4-dicarboxylic acid diethyl ester

Reaction Steps

The title compound was prepared in analogy to the procedure described for Step L3 but 2-bromo-5-[(4-chloro-phenyl)-hydroxy-methyl]-1-isopropyl-1H-pyrrole-3,4-dicarboxylic acid diethyl ester (Step BM2) and 5-amino-3-chloro-1-methyl-1H-pyridin-2-one (Step E5) were used instead of 2-[(4-chloro-phenyl)-hydroxy-methyl]-1-isopropyl-1H-pyrrole-3-carboxylic acid ethyl ester and 3-amino-5-chloro-1-methyl-1H-pyridin-2-one respectively. The title compound was obtained as a blue foam. tR: 1.28 min (HPLC 3); ESI-MS: tR=1.25 min, [M+H]+ 612/614/616 (LC-MS 1); TLC: Rf=0.17 (2:1 EtOAc/heptanes).
