Versuchsvorschrift

tert-Butyl 4-(2-(4-fluorophenyl)-2-oxoethyl)piperazine-1-carboxylate (8.65 g, 26.8 mmol), 4 M HCl in dioxane (6 mL) and dioxane (20 mL) were stirred at 43° C. for 1 h. The solvent was removed under reduced pressure and the residue was dried in a vacuum oven to yield the title compound (5.29 g). Exact mass calculated for C12H15FN2O: 222.1. Found: 223.4 (M+H+).
