Reaction Steps

Trans-{4-[2-(4-Benzo[d]isoxazol-3-yl-piperazin-1-yl)-ethyl]-cyclohexyl}-carbamic acid tert-butyl ester (1.3 g, 3.03 mmol) was dissolved in 3 ml dichloromethane and 4N HCl in dioxane (15.2 ml, 60.7 mmol) was added. The white suspension was stirred for 4 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 (1.2 g, quant.) [MS: m/e=329.2 (M+H+)].
