Cyanoacetic acid → HCID 67971142, compound

Participants

Reaction Steps

To 7.0 mg (0.08 mmol) cyanoacetic acid in 1 mL DMF 35 μL (0.20 mmol) DIPEA and 29 mg (0.08 mmol) TBTU are added and the mixture is stirred for 10 min at rt. Subsequently 29 mg (0.09 mmol) (S)-1-{4-[1-(4-ethoxy-phenyl)-piperidin-4-yl]-phenyl}-ethylamine (XIII.1) in 1 mL DMF are added and stirring is continued over night. The mixture is filtered through basic aluminum oxide, followed by washing with DMF/MeOH (9:1) and concentration in vacuo. The residue is purified using reversed phase column chromatography (water/MeOH, 0.1% TFA) and the corresponding fractions are concentrated to yield the desired product.
