Participants

Reaction Steps

To a suspension of NaH (170 mg of a 60% dispersion in mineral oil, 4.25 mmol) in anhydrous DMF (20 ml) is added 2,2,2-trifluoro-N-{4-[(2,2,2-trifluoro-acetylamino)-methyl]-piperidin-4-yl}-acetamide hydrochloride) (500 mg, 1.4 mmol) followed by 4-bromomethylpyridine hydrobromide (350 mg, 1.4 mmol). The reaction mixture is stirred at room temperature for 3 hours. The reaction mixture is quenched with sat. NH4Cl solution and is concentrated in vacuo. The residue is purified by column chromatography (basic alumina, MeOH/DCM) to obtain 2,2,2-Trifluoro-N-[1-pyridin-4-ylmethyl-4-(2,2,2-trifluoro-acetylamino)-piperidin-4-ylmethyl]-acetamide as off-white solid; [M+H]+ 413
