10.8 mmol of 4-benzoxazol-2-yl-piperazine-1-carboxylic acid tert.-butyl ester were treated with 30 ml of a dioxane, saturated with gaseous hydrochloric acid. The heterogenous mixture was stirred at room temperature for 1 hour, before evaporation of the solvent. This yielded the title compound as a colorless solid.
