Cyclohexaneacetic acid → 1-(Cyclohexylacetyl)-4-[3-(trifluoromethyl)pyridin-2-yl]piperazine

Participants

Reaction Steps

Coupling of 1-(3-(trifluoromethyl)pyridin-2-yl)piperazine (271 mg, 1.17 mmol) with 2-cyclohexylacetic acid (100 mg, 0.70 mmol) was carried out according to a similar procedure described for example 19A using N,N-dimethylformamide (1 mL) as solvent and benzotriazole-1 yl-oxy-tris-(dimethylamino)-phosphonium hexafluorophosphate (700 mg, 1.56 mmol) as coupling agent. 1-(cyclohexylacetyl)-4-[3-(trifluoromethyl)pyridin-2-yl]piperazine was obtained in 56% yield (140 mg) as colorless oil.
