Versuchsvorschrift

To a solution of 2,4-dichloro-5-fluoro-pyrimidine (0.43 g, 2.58 mmol) and racemic methyl-3-amino-2-hydroxy-1-methyl-cyclohexanecarboxylate acetic acid salt, 66d, (0.58 g, 2.35 mmol) in THF (10 mL) and MeOH (8 mL) at room temperature was added iPr2NEt (1.23 mL, 7.04 mmol). After stirring the reaction overnight at room temperature, the solvent was evaporated under reduced pressure and the crude residue was purified by silica gel chromatography (Hexanes/EtOAc 100/0 to 0/100, Rf=0.7 in Hexanes/EtOAc 2/1) to provide 650 mg of racemic methyl-3-[(2-chloro-5-fluoro-pyrimidin-4-yl)amino]-2-hydroxy-1-methyl-cyclohexanecarboxylate, 66e, as a white solid. LCMS: 318.16 (M+1).

Aufarbeitung

  1. customthe reaction overnight at room temperature
  2. customthe solvent was evaporated under reduced pressure
  3. customthe crude residue was purified by silica gel chromatography (Hexanes/EtOAc 100/0 to 0/100, Rf=0.7 in Hexanes/EtOAc 2/1)
