N-Methylpyridine-4-methylamine → (S)-2-{4-[4-(1-Acetylamino-ethyl)-phenyl]-piperidin-1-yl}-pyrimidine-5-carboxylic acid methyl-pyridin-4-ylmethyl-amide

Participants

Reaction Steps

To 36.8 mg (0.1 mmol) (S)-2-{4-[4-(1-acetylamino-ethyl)-phenyl]-piperidin-1-yl}-pyrimidine-5-carboxylic acid (XVII.1) and 51 μL (0.3 mmol) DIPEA in 2 mL DMF is added 38.0 mg (0.1 mmol) HATU and the mixture is stirred for 15 min at rt. Subsequent the mixture is added to 12.2 mg (0.1 mmol) methylpyridin-4-ylmethylamine and stirring is continued for 12 h. The solvent is removed in vacuo and the residue is purified using reversed phase column chromatography (water+0.1% NH4OH/MeOH) and the corresponding fractions are concentrated to yield the desired product.
