摘要:
The invention relates to an improved method for the production of chiral N-substituted N-methyl-3-hydroxy-3-(2-thienyl)-propylamine, on an industrial scale by using asymmetric hydrogenation as a key step and, optionally, a special sequence of successive steps. A catalyst system consisting of rhodium and (2R, 4R)-4-(dicyclohexylphosphino)-2-(diphenyl-phosphino-methyl)-N-methyl-aminocarbonyl-pyrrolidine is used.
摘要:
The present invention relates to a process for the manufacture of a specific indolinone derivative and a pharmaceutically acceptable salt thereof, namely 3-Z-[1-(4-(N-((4-methyl-piperazin-1-yl)-methylcarbonyl)-N-methyl-amino)-anilino)-1-phenyl-methylene]-6-methoxycarbonyl-2-indolinone and its monoethanesulfonate, to new manufacturing steps and to new intermediates of this process.
