A cold solution of 4-(3-fluoro-benzoyl)-piperazine-1-carboxylic acid tert-butyl ester (400 mg, 1.29 mmol) in 1,4-dioxane.HCl (1 mL) was stirred at 0° C. for 1 hour. The reaction mixture was then concentrated under reduced pressure and the resulting crude residue was washed with ether and dried to afford 280 mg (89%) of (3-fluoro-phenyl)-piperazin-1-yl-methanone.hydrochloride.
