Reaction Steps

A mixture of 1-(6-trifluoromethyl-pyridin-3-yl)-piperazine hydrochloride (440 mg; 1.65 mmol), 4-bromo-butyric acid methyl ester (322 g; 1.65 mmol), potassium carbonate (456 mg; 3.30 mmol) and potassium iodide (274 mg; 1.65 mmol) in acetonitrile (6 mL) is heated to 100° C. for 2 hours. The reaction mixture is allowed to attain room temperature, filtered and the filtrate is concentrated under high vacuum. The resulting residue is taken up in tetrahydrofuran (10 mL) and a solution of lithium hydroxide (119 mg; 4.95 mmol) in water (2 mL) is added. The resulting mixture is stirred at room temperature over night and is then diluted with acetonitrile (90 mL). The precipitate formed is then filtered and dried under high vacuum to afford the desired compound (495 mg; 1.53 mmol).
