Versuchsvorschrift

Quinuclidine-3-carboxylic acid hydrochloride (817 mg, 4.26 mmol), EDC (1.23 g, 6.39 mmol), and HOBT (979 mg, 6.39 mmol) were dissolved in dry DMF (40 ml). DIPEA (2.61 ml, 14.9 mmol) and bis(3-fluorophenyl)methanol (1.03 mg, 4.69 mmol) were added, and the mixture was stirred at room temperature overnight. The mixture was diluted with water and extracted several times with Et2O. The organic phases were collected and washed with brine, dried (Na2SO4), filtered, and evaporated. The residue was purified by flash chromatography (DCM/MeOH=9/1) to obtain bis(3-fluorophenyl)methyl quinuclidine-3-carboxylate (874 mg, racemic mixture).
