Versuchsvorschrift

4-(4-fluorobenzoyl)piperidine (trifluoro-acetic acid salt) (0.020 g, 0.062 mmol) was solved in 1,2-dichloromethane (0.300 mL) and Quinoline-4-carboxylic acid trans-[4-(2-oxo-ethyl)-cyclohexyl]-amide (0.020 g, 0.067 mmol) was added. Methanol (0.200 mL) was added to the mixture and it was stirred overnight. Sodium triacetoxyborohydride (0.024, 0.11 mmol) was added to the clear solution that was stirred 10 hours at room temperature. The mixture was concentrated to dryness and the residue was taken up on methanol and purified with preparative HPLC on reversed phase eluting with acetonitrile/water. The combined producted fractions were evaporated under reduced pressure to yield 0.03 g of a white solid (0.06 mmol, 99%). MS (m/e): 488.3 (M+H+)
