Versuchsvorschrift

Compound 52.1 (22.58 mmol) and 4-iodo-1-(2-pyrrolidin-1-yl-ethyl)-1H-pyrazole (22.32 mmol) was dissolved in DMF and degassed with nitrogen. To this was added Pd2(dba)3 (0.23 mmol), Ph3As (0.46 mmol) and CuI (1.16 mmol). The reaction mixture was heated at 80° C. for 6 hours, concentrated to dryness and purified by flash column chromatography on silica gel (10% MeOH in dichloromethane) to provide 4-chloro-6-[1-(2-pyrrolidin-1-yl-ethyl)-1H-pyrazol-4-yl]-thieno[3,2-d]pyrimidine (compound 52.2).

Aufarbeitung

  1. customdegassed with nitrogen
  2. concentrationconcentrated to dryness
  3. custompurified by flash column chromatography on silica gel (10% MeOH in dichloromethane)
