4-(5-Fluoro-benzo[d]isoxazol-3-yl)-piperazine-1-carboxylic acid tert-butyl ester (22.7 g, 70.6 mmol) was dissolved in 40 ml dichloromethane and 4N HCl in dioxane (264 ml, 1.06 mol) was added. The white suspension was stirred for 16 hours at room temperature, diluted with diisopropylether and filtered. The crystals were washed with diisopropylether and dried for 1 hour at 50° C. and <20 mbar, to get the desired salt as a white solid (18.2 g, quant.) [MS: m/e=222.3 (M+H+)].
